Basically this novel is abt the scientist MC and his experiment ML. MC successfully created ML and cared for him since he was still a fetus until a full grown man. ML develops deep love and turns yandere and wanted MC to be his lover so bad.

MC is just a really broken man, he was betrayed and not loved for almost all his life and only experienced one relationship with the Cheater chen xuan, he's basically deprived of love and wanted love eventhough it was fake. He couldn't accept ML cs bruh MC sees himself as a father figure to ML and it cant changed so easily. I just feel immense pity for MC, he's so hurt. Though he had his wrongdoing, I still like him. ML too, he's an aggressive yandere but really he's good boy, he didn't r*ap* the MC even once, he really respects him. Guys just dont look at the characters at surface lvl, try to understand their way of thinking and their stand...

Feng Yeran died, I could totally relate to all the emotions Feng Hua went through, the pain, despair and fear, knowing your loved one was nearing their death.

although I wouldn't really call him a split personality since the basis of DID (dissociative identity disorder) if fully on a human mind, although our little monster has emotions like humans he isn't and therefore the people he created like Sean stems from parts of him but it isn't DID. Which is better since if it was actually DID the sh*t the happened wouldn't have actually made sense lol

As much as they both would have loved if they met as humans and healthy ones their story would have never worked if that was the case. Feng Yeran had to be Feng Hua's creator, Feng Hua's love and obsession stems from his biological nature, if anything their love could either be called fate or coincidence. I liked how f*cked up their relationship was, it kinda showed how twisted and connected human emotions can get when not healthily understood and separated, like the line between love and attachment. Feng Yeran started out as a very selfish scientist, he wanted to make a legacy before he died and ignored the ethics of what they were doing. Feng Hua was a child, a "yes" from a child isn't consent when you're asking them if they "ok" being mutilated. He was accepting all the experiments for Yeran, then after getting what Yeran wanted Hua was neglected. Hua's understanding is definitely still childlike, he doesn't understand his own emotions fully nor does he understand Yeran's. A good example would be that an adult in that situation would not have because they understand the complexity of the situation but Hua's more demanding.

Skipping some stuff I really think they could have expanded on Yuren's trauma that Hua caused, u know all the deaths. But I'm fine with how it is, how I see it Yuren really has nothing else and chooses to keep all the good times with Hua rather than the bad because his attachment to Hua was the only thing he had left, I do think he did love Hua tho. I like how it ended and they were both pretty f*cked up in their own right. I do think that him knowing he was dying influenced that decision but that goes the same for Yuren's initial situation from the start, he needed to be dying and he needed not have a good family support for Hua to be born. The same way Hua's actions made sense, because he was not human and because he was never treated as one

at least when he's in his right mind, lol. I won't spoil too much but once you know what's going on, the rest of the puzzle pieces fall into place pretty quickly.

I felt so bad for the ML when reading about how he suffered during all those cruel experiments just because its what the MC wanted. The MC really didn't deserve him. Even though I knew the MC was eventually going to die, I had some sliver of hope that ML would figure out a way to save him. The way ML suffered from his multiple personalities and new worlds just broke me... The ending was so bittersweet. I hope that after his last world is over, that he and MC found eachother in the afterlife.
