ML was the Medical Sage who had two disciples -and one of them happened to bee the original-FL, who is a genius in using poison. Like always, MC was the fiance of the original-ML who had dual identities in this arc. The plot in this arc went typically like it did in all other arcs, except this one got stretched because in midst of the arc MC's family is killed by the original-ML and she's the only survivor. She wanted revenge, and planned to counterattack against the original-ML after she marries the Medical Sage (aka our ML). She almost succeeds, but then the original-ML spills the beans, and it turns out that it had been her husband (our ML) who had ordered for her Family's massacre. The plot thickens, and more plot twists appear at that point which I don't really wanna spoil but there's one thing I'd like to say-

For an ML who's supposed to be the Second Male Lead of the original stories, he somehow turned out like the Final Villain Boss who only had MC in his eyes. He'd do anything for the MC.

Anything.

A big pe*vert, clingy af, and downright devious

His gentle persona is just a facade because that's exactly the MC's type. He's literally using a honey trap to manipulate her into doing what he wants.

And even after MC discovered the truth, she thought it was fine since it's only affecting her and not hurting anyone else.

Girl, you do you, but I think that's insane.

How does he know it's her type? Because they know each other IRL. It was the personality she fell for when they first met, so he just kept using it since it was super effective.

She's actually pretty flexible and mentally strong for a person target by a yandere. But once her bottom line is crossed, she becomes an entirely different person, be it by breaking down/becoming indifferent/cold.

Her bottom line has 3 priorities:

1. Her family
2. Her child
3. Her own life

MMC is constantly testing how far he can push her before she tries to leave him for good. Once he figures it out, he crosses it over and over to wear her down. By the end of the novel, she's almost numb to everything he's done and whatever he will do in the future.

Examples:

1. 1st time he killed her parents, she left him by spending all her hard earned points on an incurable poison, choosing to due and exit the world right in front of him. So ML adapted, improvised, and overcame. In future arcs, instead of killing her parents outright in order make her stay with him, he threatened her instead. Nice one bro
2. 1st time he used their child to threaten her into staying with him, she committed su*cide again. Again, adapt, improvise, overcome. In the same arc, he brought her back to life, but changed his approach! He erased her memories and pretended they never had a kid. Good job bro
3. 1st time he planned, not threaten bro come on, to kill her so he could have her all to himself, she mentally broke down. She cut herself first before he could anything. MMC's 3000 IQ at work again, he amazes us once again by erasing her memories of that arc and sent her off to another world. Good job

in one arc the male lead is a good hearted compassionate guy but was framed and hurted by his own master due to ugly jealousy.

In that world he waits for 700years for our MC to reconcile. He loved her so much that he couldn't bear not seeing her and literally takes out his ribs to make puppets like her just to see her figure infront of him. He loves her so much.

And that's the only arc in which he never behaves like a psycho to tie her in his cage

Until the last few arcs, the MC will usually not fall for her fiancee (the storyline she transmigrated to's "male lead"). I think she fell for the wrong guy maybe 3 times in all 2k chapters? Once with the 3rd male lead, twice with the story "male lead" who lied about his name so she didn't know he was the "male lead". Usually the story "male lead" will not like her, almost to an irrational extent. Many times you'll be left wondering why he likes the story's "female lead" who is a much more boring, dull, annoying character and has a lot less chemistry with him. The only exception to this is the last few arcs, where the MC kinda fell for him, and he fell for her but is a s*um that also fell for the Mary Sue "female lead" and is indecisive. It's moments like these where it looks like the only reason he fell for the "female lead" is because the story plot had them as an original couple - they had zero chemistry. Lastly, the constant is that the actual ML will become obsessively in love with the MC, and dote on her. Depending on how he handles his obsession, the arc is a HE (or not). If he kills her family, it will always be a bad ending for him, as that's her bottom line.

the arc where she's neighbors with the disabled ML, and it turns out that he fell in love with her at first sight and had been photographing her secretly since day 1 and making a photo shrine of her, and spying on her with a telescope. He also mu*dered his abusive mom, and saw MC secretly helped him reburry the body, resulting in him falling for her even harder. The Xue Ran cultivation arc, while not my favorite, was probably one of the more horrifying and plot twisty ones. ML went final boss in that one and literally left a psychological scar on MC that resulted in her ACTUALLY REMEMBERING his name after the mind wipe from the System. It was quite hilarious to see the next arc when she whispered Xue Ran's name and remembered him, and the current ML of the arc goes insane from jealousy about who the hell this man she's talking about is. This arc is also one of my favorites as well - ML was MC's "uncle" who, it's later revealed, planned EVERYTHING from the start just to ensure that MC would fall for him and become his wife. And when did this start? When he held MC as a baby in his arms. The "main villain" of the storyline can't help but call him a madman, and everyone in the room that hears this is horrified with him. It's just so over the top and funny. The arc where ML was a eunuch was a rather plot twisty and interesting one as well. Bonus points that the author actually did research on the fact that a eunuch could still have a smexlife with the MC, although he'd be less sensitive *cough*. Plot twist that there's some time travel, and future self for ML freaking KILLS present self him and replaces him so he can be MC's husband in this timeline. Another favorite arc was the one where ML was the psycho mental patient cannibal serial killer who took over the mental hospital and pretended to be the doctor. He went from wanting to kill and eat MC to wanting to mate her. I laughed pretty hard at when it revealed ML's plan to let her escape confinement, then hypnotize the story "male lead" to shoot him, so that MC would feel bad and stay with him. Only for her to exceed his expectations and ask him to come with her and leave the island. But he still gets shot, and has to wait a year for his wounds to heal, resulting in him BLAMING the poor guy he hypnotized, despite it being his own plan, because he's unreasonable.

plot twist about Guardian, the zombie apocalypse theme, the desolate atmosphere and utter creepiness of the MC breaking out of the illusion in the ice cream shop... I kind of wish that was the reality that lurked outside of the QT System. I know it would never be a Happy Ending if that was the reality, but I think this actual reality for the ending is more cliche. Oh, MC was in a coma from a su*cide attempt, crazy ML made some sort of medical hypnotism program thing to help her eventually wake up after 6 years. That's like 99% of these QT happy ending stories. I think the Guardian program AI that trapped her in an infinite virtual simulation in an attempt to get her to realize her feelings for it and return its feelings after mu*dering everyone else in her city is such a fresh take, although it is very dark.

MC's target in the first world is the ogML's secretary, who is the second ML. After meting him under forced circumstances, she then meets him at a party. Where she throws a tantrum and forcefully leaves with ML. Then, she confesses to him. Girl, you have met him once before this, and that meeting didn't even go well. Any normal man would reject her and label her suspicious.

For example during the ancient era as we all know, she is a modern era women same goes to the original FL but the original FL are equipped with brains and knowledge and helps during the war but our

1. Modern CEO novel: ML's is og ML's secretary and half brother. He has a mild possessiveness, nothing excessive because of this world's setting.
2. Historical novel: ML is enemy kingdom's emperor. He kidnapped FL.
3. Historical novel: ML is a son of a qinwang, he's blind but very good at hiding it. I don't he ever wrong FL in this arc, but at first he wanted to make FL his specimen.
4. Modern school novel: ML is FL's sickly disabled neighbor. He killed his mother when he knew his sickness is his mother's scheme. FL help him hide his mother's body haha, she thought he doesn't know what she did. He has stalkerish behaviors; photos, tracking, etc.
5. Virtual game novel: ML is a hacker. Rather crazy, basically only feel that kind of urge towards FL, so he's rather pe*verted lmao. He has excessive stalkerish behaviors, you named it, cctv, FL's phone, computer, laptop, home cable, she can't escape. He even try to kill himself as a threat to FL so she won't leave him, he even broadcast it on entire city, crazy.
6. Wuxia novel: ML is a sage doctor. I don't like this type of novel so I mostly skim this arc except the part when ML and FL interact. He's a secret villain boss haha, the first bad ending. He kill FL's entire family to get her. Even when she's pregnant with his child, she's unwilling to relent to him. She kill herself in front of him a few months after giving birth.
7. Historical novel: ML is a prince regent, FL is an empress. I love this arc but this arc's ML will really challenge your bottom line. He fell in love with her the moment he saw her (she's literally a newly born baby!). So yes, he scheme for FL's affection right after that, he frickin raised her for god sake. 10+ years worth of scheming for a schene where he can sacrifice himself fot FL so he can at least bind her emotionally to him (unnecessary, after all, she really loves him. But he doesn't know it and want extra guarantee). In the extra, his daughter found out about his secret room where he keep FL's enemy as specimens. Even his aide thought that he would kill his own daughter at that moment. In the end, he erased her memory so FL won't find out about it. You can see his callousness towards his own flesh and blood.
8. Modern showbiz novel: ML is an amnesiac ghost. Basically he used to obsessed over FL so much when he live (he's at death door, sickly). He's a certified psychopath in this arc, when he was about to die, he basically schemed FL's demise so she would accompany him even in death. When he die, his soul split in two. The black one inherited his memory, obsession, and his goal to kill FL, the white one got an amnesia but still inherited his love for FL. In this arc, we finally know that FL can get blackened after all, after she knew her boyfriend want to kill her in the name of love. She even said that the moment she doesn't love him anymore, she would tell him to go die so she can live peacefully. The ML say yes to that. Both of them are cray cray.
9. Cultivation novel: ML is the sect's head disciple 700 years ago. The FL can travel through time. Very cute, I love this arc's ML, very pitiful too. He wait his wife for 700 years, in loneliness he created FL's dolls from his ribs and separate his consciousness to make the dolls slightly more FL-like. Of course he never manage to create an FL-like doll, only the appearance and not the behaviors. He even forget the passage of time so he missed the FL's birth and only remember it when she appears directly in front of him. We can see his callousness towards his daughter again, he's a distant father here. He got angry when his daughter wear red because it reminds him of his wife, though never hurt her, you can see it from his hands-off parenting method.
10. Modern novel: ML is FL's adoptive brother. I like this novel's og FL, at least she's a sincere person especially when you compare her to her brother (ML). Basically, he made FL promise him to always protect his sister no matter the cost, he'd regret it down the line because it cause FL blindness. Yeah, in the end he even throw away his sister's happiness because of the previous og ML talk of marriage with FL (of course it never happen). Mild paedophilia, the ML is 22 yo when he started to show interest towards his 15 yo FL.
11. Interstellar novel: ML is an artificially created human. He used to be sexually ab*sed by people (tho at first he never react because he doesn't know anything about emotion), then he got fed up and blew up a planet. He act as a warden and drove everyone to su*cide and created a solo played script. Basically he's the screenwriter
    director, and actors. I think he's lonely and pitiful so he created other robots with pieces of his consciousness to act as if they're in prison and wanted to go out. Oh yeah, this is ABO world. Nothing excessive in this world, I think the ML is sweet.
12. Historical novel: ML is an assassin guild leader-cum-FL's-brother. He swaped his underling to act as him for 10 years in the palace. When he said he's the real prince, my thought was 'damn, real in*est?!'. But no, they're not actually biological sibling, his father is not the emperor. He even said that in case they're real full blooded siblings, he'll find a way to convince FL that they're not just to get her. I forgot to mention that at first he want to trap his sister (FL) in his dream and to never wake up.
13. Modern cultivation novel: ML is a hybrid from god and demon race. FL memory was sealed so at first she fall for the 3rd ML but then her memory came back. I think he's very sweet in this arc too.
14. Cultivation novel: ML is something akin to the world's consciousness. He's practically omnipotent in this arc, I hate his callousness here. This arc is very convulted that I can't explain it. I pity his child, he directly said to her that the value of her existence is to make her mother happy, so if she want to live longer, she better not make her mother unhappy. FL repeatedly lose her memory because ML resurrect her everytime she try to su*cide. Basically she's very distrustful towards ML in this arc. She thought he want to kill their child (I can't blame her for thinking so when he persuade her to abort. He said that child bring conflict and divide her attention). We know that FL has strong aversion towards immortality, but here, the ML is practically immortal. He wants to keep her by his side forever so he keeps erasing her memory, make her confused, make her doubtful, basically never let her thought about completing her mission so she can keep staying by his side. This force the system to directly intervene (previously it was sealed by him), it appear in front of this arc's ML. Dundundun, they're the same person.
15. Modern school novel:

killing, mind-control, manipulating, stalking, self-harm, hypnotism, waiting for centuries, locking up MC, time travel, world creation, getting past life and death boundary, basically becoming a god, recreating a body for MC, using other people to revive MC, and many many more

• ML kills FL's whole family and becomes her enemy
• ML imprisons FL and no matter how many times she commits su*cide she can't escape
• ML is an assassin sent to kill FL and they fall in love during the three days before her death occurs

FL falls in love with a disfigured bandit. Since she's the daughter of the county lord, she's worried about how to make her parents agree. Oops! Jk. FL is actually a ghost who has been dead for 300 years and has the ability to create fantasies around her, so all the plot with the origFL and ML are fake. Haha jk! This was actually just a simulation to resolve a bet about whether FL would still love ML in a future where he abandoned her to save a town of people.

In real life where they're married the FL is in coma; Nd she did that by trying to kill herself becuz she couldn't handle the ml's morals in reality as he kept doing things which where not acceptable by her and made her hopeless but she still loved him. In the end she chose to escape reality and the ML went crazy yeah. He put her in a psychological stimulation where he kept lowering that bottom line of her's to make her accept the things he could and would do. With every arc she was more nd more accepting of him but she also showed him some lines he just couldn't cross and he used that in reality after she awoke from her coma to keep her restrained mentally and emotionally. He even had a daughter to keep her from trying to kill herself nd blackmailed her about her parents and friends. He did all kind of sh*t and in the end she agreed in living with him alone like in an imaginary cage of many emotions. After going through everything when she was in coma she understood him a lot better and her empathising made her stay. She also accepted his crazy behavior and thus in the end she says that people might think she sacrificed herself to restrain him from harming others close to her but that's not true. Because she had the memory of her transmigrations she compared the bad arcs with reality and realised it wasn't all bad now. Meaning lu Chen hasn't killed her parents or her daughter and he hasn't done anything unforgivable for now and that's what gives her scope to continue her relationship with him and 'love' him. At that point she was happy that way in that cage. He wanted this outcome so that she never escapes him again, he kept lowering her bottom line and it worked.

FL is in coma and doctor diagnosis her going to be coma for the rest of her life. Then the ML make a system so she could wake up. Like the mission is not important guys the real thing is the way she feel like want to wake up

MC tolerates psychopath ML very much. He kills, she hides the corpses. In fact, they are both yandere for each other, only that the MC have a bit of morals and won’t kill people in a whim. She is also very clingy to ML every time they meet, she seduces him and flirts with him until ML can no longer resist. There is this Ju Mian arc where he basically treats MC as a tool and a fool so that his sister (the origFL) would have a good life. When he decides that he actually likes FL, FL instantly clings to him. I’m sorry, but I just can’t like that kind of weak female lead.

ML says if he has to die, FL will have to die with him. If FL likes their children more than him, he will unhesitatingly kill their children. If FL’s family blocks their love, he will kill FL’s family. Keep in mind that ML would sometimes deliberately hurt MC emotionally just to reach his own goal—which is for the two of them to be together, no matter if he drags her to hell with him first.
