So some people mentioned that it didn't make sense why the system sacrificed itself for the MC and ML. In the extra, it was explained that when the system first saw MC, they knew that he was his host, and they really loved him (in a familial way, as the system said that they felt like an elder watching their child). The system's name is Shun (if translated properly) and he never knew why they were called that. The main system said that the name was some kind of 'mark' (idk MTL probably lost the meaning in translation). Later we find that the system was probably a family member of MC, I think their family cat (seen in MC's flashback later). In the system's flashback, they said that they remember a cute chubby boy running towards them and calling them 'Shun' and that was the first word the chubby boy said. From that moment onwards he "vowed with nine lives (because cats have 9 lives) and would take good care of him", and said that "Mom and Dad, [even if] you are not here, I will protect him". (I'm getting teary).

Also to make you guys feel better, the author hinted in an extra that the system reincarnated into a kitten. One of the girls in the orphanage named them 'Shun Shun'/Er Shun, which is why MC got reminded of his family cat in his previous life.

Spoilers: When the MC takes some time to self reflect on his behaviors, which have become self destructive once he reaches a point of mental conflict, it was actually a really poignant look into his character and thought process. MCs breaking point in the novel has him reflecting on the similarities between himself and the OG host. Had his circumstances been different, he feel he likely would have turned into him. It didn’t excuse OH hosts actions, but was instead a look into how the author views relationships and how the people in our lives can have a massive impact on how we approach the world. It felt really raw and was probably some of the best writing in all 150 ish chapters.

I feel like a lot of their relationship moments (aka when they officially got together) is just them talking on the phone LOL. A lot of long-distance pinning stuff.

THE FRICKING LAP SCENE AT THE START. AND ALSO THE SCENE WHERE THEY HAD TO KISS INFRONT OF THE OTHERS AND THE ML GOT RLY INTO IT. WEW. THOSE WERE THE BEST.

So apparently the ML suddenly has some terminal illness cause he was reborn twice. And initially MC wanted to use the soul fluid (?) but system said it wasn't allowed. So he wanted to do some conversation treatment aka giving half of his lifespan? Didn't really understand this part entirely cause I MTL-ed it. In the end the system, z48, sacrificed himself? And both MC and ML are happy and healthy. But I felt like the thing with the system was super abrupt LOL. Apparently system has liked the MC this whole while and he's actually the MC's dead pet cat (in the MC's og world). Honestly felt really weird cause the system didn't have a significant role throughout the novel, it just appeared from time to time. I never really felt any deep affection, even if it was platonic. I feel like the author just wanted to make the ending deep so he/she randomly placed it.

I think his actions towards ML is pretty justified. It was established in the beginning that he needs to act out every scenes perfectly if he wanted to live. Once or twice, things can be altered but events regarding the ML is pretty hard to interfere with because they are direct contact with specified lines.

At the end of the day, him too is also a normal human who only wanted to live peacefully so it makes sense for him to follow the instructions although not si faithfully but enough to minimize the damages.

We can also see ourselves from out perspective that he’s slowly falling in love with the ml. But the situation does not permit to do so and the risk is his own life. It’s a hard decision.

gave up his life in his original world to stay with the ML. And that was a really important and admirable thing the MC did there since he's kind of admitting that the ML is more important than his own life

breakup part, long separation, and even all the little plot points when the MC had to let the ML get hurt, but he already had feelings and pitied the ML, f*ck my heart hurts for him. AND the car crash part. Like aghfghs. Sorry for going off there.

let go of Song Xuanhe when she realized that he wasn't good for her and no matter how much she cared for him, he wouldn't care for her. I live for the part when she wiped off her makeup, stood up, threw her f*cking handkerchief at Song Xuanhe like the queen she is.

i think MC can accept ML sooner. I understand that he wanted return to his world so he didnt want to give a hope to ML but I think The author could have moved the story forward faster And there was no need for many events in the story. Like going to another country. There are many useless event. And we could enjoy their love life more than this. Its really short. I wanted read more about their peaceful life. And I happy when the system reborn in world again. I feel sad when I read its part. And I wanted to read more about ML's previous life. His interaction with his 7 bf. What's happened to him in his childhood. How did his Stomach get hurt something like this

i dont undrstand many things, maybe its because I read mtl or something else but whats the reason that MC transmitted to story? I really didnt understand. Cause the story was uncomplete? And its not like other many worlds novels that MC transmitted to many worlds to complete his mission its only 1 world so I couldnt accept that there is no reason. And its not like that this is MC's Previous life or he write something for author or there is an evil system I really can accept any reason but there is no reason . Maybe im illogical. I think I want more reasonable sake. Another thing is what the hell is with the novel's name really? And a 7th bf is a hacker and hate ML at all, only 1 bf really love ML in this world but 3 of them didnt meet MC so why they didnt chase ML ? In this novel system said its because ML and MC are in public relationship and many people didnt chase ML for this. But I dont think its the reason. I mean others even didnt have good impression on ML . When you like someone and he has a bf you should at least keep a good impression on that person but 2 of them even hate ML so it isnt a good reason and so whats the reasson behind the novel's name ? And why author didnt complete the story? Its really because she didnt know who would be the real ML's bf? Its kinda ridiculous you know. So I cant understand this matter too. But im glad that it has a hp end and another question that I have is who is the Protagonist in the world now? If this isnt ML then who can be Protagonist? Can we have a novel world without Protagonist ? I have many other questions too, but im too lazy to write them. Maybe after I read the complete version with good translation not MTL I can find their answers,

I actually prefer the ML before his rebirth. He's smart, pure and innocent, much more likable.

The novel was good, MC and ML interaction and role in the novel is good.

We get a lot of hot kisses here and there but sadly only 1 snu snu which is near the end of the novel! BOO this suck!

The ending for the novel IS a big disappointment for me! It ended rather boringly, plain, and rushed. I really hate how it ended!! Like really, how the author just gonna end the novel like this!! F#ck this ended it s**ked as$!!!!

Also near the end of the novel MC's fam suddenly isn't mentioned again! And as for the s*um dad I feel so much hate on how he didn't get a bad ending! As for ML's fam, especially the mom! I hate how the novel ended without us seeing them suffer! F#ck ML's mom and bro!

for some reason, the original love interests that were supposed to be interested in ML seems to be interested in MC instead? Like please stay in your own lane (because we all know ML falls first and I rather see MC's reaction to that). But no, so far by chapter 40, 2 out of 4?5? of the 7 love interest seems to be more interested in MC. I don't really like it. Maybe it's a personal preference. But that added on to the fact that there's not much development between MC and ML (they're not even together half the time), I'm starting to lose steam here. And I've been reading the other reviews here, they get separated too? That's just too much... Not sure if I can hang on.
