Why can't the son just live in the parallel world? Also I can't help but see the father as a brother cause he doesn't age at all, he looks way too young to be a father in his late 30s.

My aunt is from Hiroshima. She was 16 in 1942 when the bomb dropped. I met her when she was in her 60's and I swear to God Almighty, she didn't look a day over 30! She is in her 80's now and has only recently started showing wrinkles and grey hair. Honestly, I am green with envy over this. I'm 48 and look twice her age!

I think the story is more complicated than we think it is. No matter what, Akane will always feel as a rebound. Keisuke himself is still confused whether he likes Akane or that he sees Mei in Akane. I mean, it really can't be helped if he feels so cause their face is just too identical. I'm not even sure if he does like Akane for the way he is since Akane always reminds him of Mei.
That flashback of Mikuni and Shouta's high school life was so short but it was enough to break my heart into pieces :'( unrequited love sure is painful but the regret that follows after you miss a chance is even more heartbreakingly painful
Well actually I kind of think so too, can't really call it an unrequited love. And please keep in mind I don't blame anybody here lol. I just feel bad for both parties for not properly confessing to each other but when you think about it, shouta thought he missed a chance and regret his decision for letting go, but mikuni on the other hand, didn't go for him either after that incident :/
