Would have legit cried if I was Rio and heard him say " I don't need Rio.."

Bruh bye
But I also felt bad for him since Rio didn't want to stay with his father at all and went back with keichi many times and didn't miss his father at all. So you can't really blame him for not wanting Rio in his romantic private wedding he didn't want his brother too so yea I can't really blame him when his son doesn't even want to stay with him.
Does anyone know other mangas like the first one??
if you want something with 3way then the only thing one that comes to mind right now is this http://www.mangago.zone/read-manga/futari_no_musuko_ni_nerawarete_imasu/
