This ML is the Final Boss of emotional warfare. Gaslighting? Manipulation? Emotional whiplash? He's sweet one minute, unhinged the next, and I just sat there like 🧍‍♀️ "Yes, king, ruin my life." And the fact that he's the omega and the one topping?? Revolutionary behavior. This is the first omegaverse I've read where the omega is the manipulative, controlling, borderline abusive one and somehow I ended up loving it way more than I should. I fear I need therapy.

The dynamic between the ML and MC is addictive. I was flipping... more>> pages like I was on something. Their relationship is a disaster. A beautiful, chaotic mess. I just couldn't stop reading, it was like watching a car crash in slow motion but the car is sexy and the crash is mutual obsession.

Also, the yandere energy of this ML is off the charts. He's just sooo intense.

Anyway. 10/10. Shoutout to the translator for blessing us with this unhinged masterpiece. Please don't stop updating, I'm hanging on by a thread. <<less

So as of now, the relationship in the story is very toxic. But despite this, I still keep reading because despite the plot being semi painful, its written really well. Like our characters have a fully established personality and perspective based on their situation and experiences. Our MC who is the guide was born into wealth and power, and is obviously not gonna bend his back over someone who suddenly becomes at the top of power. Naw, he's basically content with his current life style of freedom. In all honesty,... more>> the esper has nothing to offer to our MC so he should be the one to change or otherwise leave. I have not finished, but I am interested enough to find out how their relationship will develop. Will the MC top or bottom? Or do they switch? <<less

It's a good light read despite the heavy themes. And by "heavy themes" I meant coercion, harassment, kidnapping, dubcon, imprisonment, stalking, ab*se, attempted r*pe, physical assault, drugging, conspiracy, psychological manipulation, toxic family drama, misogyny... I'm not even kidding. For some reason or another, the author managed to package the story in a way that's not entirely difficult to digest. Maybe because it was short and things went by really fast.

Without much spoilers, I'd say the plot twist about the MC's origin and his dreams were pretty unique.

The novel has a... more>> LOT of R19 scenes (as what you'd expect of omegaverse). It's still quite different from other ABO stories though. For one, the top is a dominant omega and the bottom is a recessive alpha.

Major spoiler 1 (about their ABO traits) :

Spoiler

I expected their traits would interchange, but they will stay as is until the end. They also don't switch positions.

[collapse]

Major spoiler 2 (side story ?) :

Spoiler

Author made side stories about the pregnancy and the baby. The child looks like half-half of the main couple, but has the top's obsessive personality.

[collapse]

Overall, I give it a 3.5 <<less

At first, it's okay. But later gong turn into gwanggong and the plot got weird. It's like jumping novel to novel.

Seme is the dominant omega

Uke is the recessive alpha

What weird (also major spoiler) :

Spoiler

Author wrote normal world BL webnovel but this novel wasn't popular, but because her writing skill is good, she was hired as a novelist by big publisher company. She wrote ABO novel. Author really attached with her 1st novel ever. So she said, to broke free from her attachment, she used her 1st novel couple in her 2nd novel BUT she made the uke as a subgong villain with tr*shy personality for her 2nd novel. Ok. So the 2nd novel is about dominant omega who was harassed by rich recessive alpha, but later omega will meet another dominant alpha and tr*sh alpha will die. The 2nd novel is successful but author still feeling regret because she didn't like the story at all. So she wrote fan fiction of her own 2nd story let's call it as 3rd novel. In the 3rd novel, author made uke from 1st novel to transmigrated into a 3rd novel. So whatever, uke now become a recessive alpha villain, but because he knows the plot of the 2nd novel, he avoid the dominant omega so he can avoid dead.

Dominant omega, whose character is written based on seme from 1st novel, actually felt attracted to uke (because current uke now has same soul from uke in 1st novel). They get together yadayada. Then the unfinished 1st novel seme, went crazy over losing his uke, yes because author stole his uke and transmigrated him to the 3rd novel. So, 1st novel seme, assimilated with current seme (the dominant omega), then he went totally gwanggong. Confinement and stuff. I forgot, I think it stopped after uke realizing his past memories as character in 1st novel. Then he appease current seme who assimilated with 1st novel seme, told him that he will never leave. And in this world they will always going to be together forever and stuff. Finally seme calm down. And their souls (1st novel & 3rd novel fan fiction) assimilated completely.

What is bothering me is, what's the point of the characters??? They all acted exactly just like how author wrote it. So in 3rd novel fanfict, 1st novel couple is the real OTP, while 2nd novel seme & his family are the villains. I mean, in 2nd novel the ogSeme was a good person, but now because they live in 3rd fanfict, ogSeme turned into villain and suddenly developed himself being a rapist (he tried to r*pe recessive alpha uke). Like?

Btw, the author also transmigrated into the 3rd novel fanfict. She suggest uke that she can wrote 4th novel to fix everything but uke refused because he wanted to stay here.

How calm is it that uke realizing that he isn't even real but just a character that someone write about?

It bothered me that the villains are bad because they were wrote that way. What if they also have access to know the real 2nd novel? Maybe they will refrain from being bad and instead chose to being good protagonists just like in 2nd novel.

Author said she doesn't wanna go back to real life Korea because her life there wasn't good, but she herself said her 2nd novel is very very successful. Like????

It's confusing how all three novels are jumbled up as one. In the end, the story flow exactly as 3rd novel fanfict except the seme craziness when his soul merge with 1st novel seme.

Kinda feel bad of the villains, not because of background story or stuff. But because they have no choice but being villains, because they wrote that way by author.

Unlike other novel of isekai that we usually read, the protagonist usually white lotus even tho the original author didn't write them that way, so it mean their villain era are totally their fault, so we can just rooted for their doom. But here, it's different, the oriML WAS WRITTEN as evil, so he just acted that way.

You know, it gave me taste like this : "you don't need to struggle hard, because god already wrote your destiny to keep being poor, even tho you're working, you will never become rich"

That's how I take it when I realized that the villains are villains because the author wrote it that way.

If the author wanted, she can actually changed them tho. But she only care about her OTP and no one else. She asked about their s*x position is also weird. Then she proceeded to tell uke that she wrote him as bottom because she likes buffy uke and pretty seme. She totally treated everyone as characters instead of human. Moreover her power to be able to change anything in this world if she write another novel and post in online made her like god, but living among characters.

Idk. This ending is so weird. But I do like the 3/4 of the story

  • Oh my dear yaoi god! I loved it. Surprisingly it's actually 28 really long chapter, so if somebody is knee on long stories, than it's definitely recommended.

    Really unique style to solve the whole transmigration problem (the other novel of the author [These lunatics are obsessed with me] also got an interesting ending).

    Actually it's also different from other omegaverse concepts (dominant omega top+ recessive alpha bottom) which was an amazing idea in my opinion.

    Long, detailed spicy scenes, and cute obsessive younger lover, who gets easly jealous (and "punish" the sweet innocent bottom).

    The story is not that deep and you can easly read it in one sit, but it always stays interesting and there is a plot, and character changing. There is nearly nothing new in this novel (except the solution), it's full of clich

    s, but somehow I just kept reading it.

    It was really enjoyable, sadly there is no sidestory, and I have high hopes to the third novel from the author [

    - I tried to be rewarded by raising him well.]
  • As for the third novel... It was good. And cute and lovely, maybe a bit confusing, but again an interesting solution for the transmigration. I didn't like that the author mentioned certain thing way too many times, but the fast progress and quick solutions are definitely a good point for them.

This story is so interesting because the gong was an dominant-omega while the shou was an recessive alpha. They didn't switch position and their relationship escalated pretty quick (as I remember, they do the snu snu on chap 4) but I said pretty quick because one chapter filled with so much words its a long chapter it can be even 3-4 chapter if its in another novel. 5/5 from me!

Love the way the ML going crazy in love with our MC haha and I actually needed more of their version in 1st novel, it would be such a heartwarming story about two teenage boys falling in love 🤏🏻

[collapse]

Spoiler

Oh and I love that this story show us a bit realistic story line like how they had to go to hospital because their 'position' in bed was not how it supposed to be. I like how our MC didn't straightaway turn to be the omega one, he still an alpha as I remember (cmiiw I read this last year)
