Aoki really is the only one that seems to have romantic relationship relationships. And I'm guessing Kimura could to (he seems responsible and chill enough when dealing with outside the gym).
Im worried Ippo will end up like the coach. A guy that only has boxing in his life and never took the shot he should have at having a life partner.He sent his love to take care of his friend. Good guy move for sure but not showing a lot of ability to show a partner you want them. I like the coach but I dont believe he actually had a relation instead of endless pining which is the Ippo way.
