Idk man. I know custody stuff is different in Japan, but he was old enough that his mom still could have stayed in contact. As someone with a difficult relationship with a parent I just don't like how he's pressuring him to go see his mom. She disappeared and he hasn't heard from her in years, why should he be burdened with this? I feel like they just glossed over that. Because of course Fukami regrets what happened with his parents, but his situation is totally different.
Anyone taking bets on if they're going with:
1. Amnesia
2. Running away because he's a burden
3. Both!
Of they do any of these or both I'll riot.
Seems like you don't have to lmao
