You're underestimating the length a child would go to gain the approval of their parents.I know it doesn't fit the story but the idea that he's my dad i need to stick up for him doesn't really apply when you dad is such a massive piece of shit like kanamori. Kanamori completely abandoned wagatsuma and turned him away after his mother died and he had no where to go(iirc). Then wagatsuma goes back in time and decides to be his teenage dads lackey? I'm all form familial fealty but it has to be at least somewhat justified. This is such a weird message to send.
Kana (old timeline) did not know that Waga was his son because he was in a relationship with another woman. When Waga confronted him, he was more confused while his lover was angry with Waga and then Waga ran off.I know it doesn't fit the story but the idea that he's my dad i need to stick up for him doesn't really apply when you dad is such a massive piece of shit like kanamori.

They were also childhood friends not since teens looks like a 10 year relationshipKana (old timeline) did not know that Waga was his son because he was in a relationship with another woman. When Waga confronted him, he was more confused while his lover was angry with Waga and then Waga ran off.
Kana (current timeline) has not been bad to Waga at all. He took a beating for Waga and hasn't abused him since. Sure he is a dirtbag to other characters but he has not done wrong by Waga so it isn't surprising Waga likes him.
