Lmao, the same losers wishing for some cucking are the same people that cry whenever there is a hint of it in these stories.
Don't get mad at the MC, get mad at the author and editors for some conveniently timed shitty drama. Those people are the reason drama like this happen.
Fyi: Helping a friend get to the hospital when their mother just had big medical emergency that could kill them is maybe, just maybe more important than a competition. Especially if it looks like it's not completely over and he can still make it.
Either way, he can still see her competitions in College. Also, once again, it's the author and editors fault that (so far) he's too dumb (conveniently) to call someone that is at the competition to let her know.
So, really, you people can go read your degenerate doujinshi's if you're into that stuff. Otherwise, chill.
