They already have a relationship, a friendly one. They can't be family, he can't be her father nor can he make up for her mother. She was quite intense at first, but Kousuke had known how to draw the limits. They're there for each other, that's their relationship.
you don’t need to take my words that seriously I’m not talking about a replacement but sometimes you have relationships with people that it so close you feel at ease with them, this is what I mean. I don’t think that their relationship is romantic atm and I don’t consider it necessary, my opinion(⌒▽⌒).
Exactly! Kousuke could've let her had her way with him and just enjoy, but that wouldn't have helped her problem. they both are saving each other by being there for one another.
Couldn't have said it better ╥﹏╥
tbh I wish they could form a genuine relationship like family cuz koto definitely needs that, just not in a romantic sense. Still feel bad for the dad though nothing is going well rn
