and I could easily be wrong...but I think the seme is trying to get the uke to "find himself" again. To stop thinking of himself as worthless, lashing out, cowering, being so careless, and everything else. I'm not saying this is the right way to go about it but making him understand that there is someone out there who cares is maybe step one. Even if it's twisted - the uke will get rescued.

Yahwi might be harsh in how he expresses himself but he's correct in trying to deal with this situation. Jooin is only stirring the pot with his actions - not on purpose, but running up to Yahwi in front of a bunch of classmates and asking for a private discussion...this isn't the time or place to do that.
Not every couple needs to loudly declare their relationship to a bunch of nobodies or wants to try and re-educate them on what it means to be gay or have to live with a gossip mill churning out more and more rumors about them.
Yahwi clearly doesn't want people to know what his status with Jooin is and that's probably for many reasons - the hate, the speculation, the effect this will have on Jooin, his own family's response. Plus, I think he's trying to get Jooin to grow a pair and meet him on an equal playing level, which Jooin hasn't done yet.
Ah, drama. Cain totally created that rumor, right?
...but no nipples! Give him nipples, dammit! I just don't get how showing male nipples can be a bad thing - it just looks weird when they're topless (which in itself is not a big deal for a dude).
