School friendly yaoi recommendations?

I know what you're thinking. "School friendly yaoi? What the heck are you doing?" I have an explanation, though. In my school we're required to do something for reading and I always read fanfiction in that class. This was a requirement in a class I was in before and I read bl manhwa occasionally. I feel like I should introduce this teacher to the joys of bl because I mean I didn't get anything for my wolfstar fanfiction, the only rule he gave me was no My Immortal, so I think I'm good. Still I feel weird trying to describe what's happening in a way where it's school appropriate so just any wholesome bl please share. I prefer Korean bl but I don't really care that much, just a preference.
