They didn't have any attraction until MC is like 15+, most of his young life, MC treated ML like an idol/big bro and that quickly turn to something else when MC is older.

ML liked MC first but just waited for ML to become older. MC confessed first, ML want to wait but MC didn't want to. ML restrained himself a lot and didn't touch MC until he's ready.

I need to remind people that inside he's already 17-18 y.o and not a teen. MC is very innocent because his old self assimilated with his new self so he have the mentality of 16 yo book reality even though he already have experience of 17-18 yo original reality

He transmigrated to an alternate reality of some sort where the real him doesn't exist but he occupied another same name toddler body.

The toddler seems to be a low function autistic. And when MC occupied his body, he gets better.

BUT MC started to forget his old life and regressed mentally to a toddler mentality. It feels like MC assimilated with the body and the more he assimilated the more he forget and be healthier.

He still faintly remember his old feelings but he can't remember why.

Once he's around 16 he finally remembered all and his body was able to take the toll of remembering his old life. So by 16 his old and new life memories fully assimilated.

He went back to his original reality, turns out he's also sick (?) but gets better. He's adopted by grandpa. His gramp died and cut the ties that bind him to that reality. So he went back to book reality

It's when they're going to surprise teacher Xia at his concert. Tang family surprise ML (and the audience since this is the first we're hearing of this) with flying to see his dads concert, he barely reacts and it's revealed that they thought this up just recently so instead of being sweet and thoughtful it comes off as impulsive? They go and stay at the same hotel as teacher Xia except HE comes to THEIR door already knowing about the surprise. And then they only stay for a day and barely describe his first day of concert but we do know that ML didn't enjoy his dads performance. Then they abandon teacher Xia and hang out while he is stuck performing for the next week. Where was this supposed to be satisfying or heartwarming? And the rest of the story is like this.

I didn't expect the revelation of MC's origin at all.

To be honest, I never doubt the connections between the book and the outside world, and just treat it like an usual transmigration novel where the transmigration just happens randomly, so when the story reached that part, I was so surprised. It's very impactful.

moreover, I really like the interactions between MC and his grandpa of the outside world. Although they are poor, they are so loving. His grandpa is kind, and the MC is very filial. 😭 What a good boy. This is so touching.

I also love the side couple. The kids are very innocent and pure-hearted. I'm glad everything turned out great for everyone.

became a sick child with over protective family. He is a bit autistic (?) And fool in the eyes of others

Until this chapter, their relationship still like a brother and his little tail. There's no romantis feeling between them. They are still kids on elementary and high school. But ML already success in his bussiness, and his relationship with MC family already like a real family. I think they Will smooth sailing when come out. But they Will take a lot of time to figure it out about their feeling
