I feel the need to say that’s Not really true. Each prefecture sets 13 as the minimum to decriminalize sex between minors but it’s still illegal for adults to be with minors there. For example, in the US I believe it is still technically illegal for minors to have sex with each other. It’s just not something that police actually do anything about. But no, japans age of consent is NOT 13 and each prefecture sets it own age limit.

why’s the father so homophobic? i don’t like this weird homophobic subplot that’s going on here

I mean sure, he doesn't want his son to be gay, but being homosexual wasn't period typical, it was a foreign thing. And I don't think that it's a homophobic subplot or that the dad is homophobic, he just wants his son to live a good life. And I don't mean to say that being gay is wrong, I'm just saying that in the time the manhua takes place in, being gay and adopting a kid because of it would ruin everyone involved.
Plus, adopting wasn't period-typical as well, usually, adoption was only if it was the child of deceased family members, or you simply needed a child.
if one more misunderstanding happens, i’ll smash my head on the wall.
