My feelings are the same. Can't believe a person like that exists and gets forgiven by people around him. I was so happy when the son was yelling at him saying he hates him. He doesn't deserve any of those nice people.
I wish I had read your comments so I didn't have to waste a full 3 hours of my life...Urg, i need to read something nice to forget this thing.

Shitty manga with a shitty ending full of shitty pairings. Tetsuo is the worst kind of person, indiscriminately hurting others because he's been hurt and can't handle his emotions like a fucking adult, why does he deserve a happy ending that causes 3 other people pain? After stepping all over his best friend's feelings, sleeping with a guy who really liked him and then insulting him horribly even though it all was HIS fault, then falling in love with and stealing away HIS SON'S best friend and longtime crush? Why does he get a happy ending????
tldr; shitty manga with shitty ending
