I know it's fucked up, but I want him to end up with grey haired dude (hyeonje?). Jingj is...

Nah hes crazy

Grey haired dude is crazier than jingi

Yeah, but I feel like he can be tamed, whereas Jingi will always do whatever he wants no matter what.

Keep in mind Heongjae is tame because Jingi has been the one controlling him and restraining him so far. When Heongjae tells Jingi about what he actually wants to do to Myeonggi like cut off his skin, even Jingi gets creeped out. Re-read chapter 23, specially on page 17.

I do remember that part. But, I don't think he'd actually do that, because at the end of the day he doesn't want Myeonggi to hate him. And, I think it's the opposite - Heongjae abuses him because he's spurred on by Jingi. Without Jingi in the picture, he might be able to have a relationship with Myeonggi. Not a normal one, but I think with a little affection, he'll learn not to take things to the same extremes as Jingi. It seems like most of his life people have despised him, and even though his brother kind of watches out for him, it's still not a great relationship. So it's possible that with some actual affection and human companionship vis a vis Myeonggi, it could really turn his character around. But now that I'm thinking about it, it's probably unlikely, because that would require Myeonggi to have feelings for him, and in the last chapter he seemed wholly uninterested.

Also, I forgot to add - I don't think he seems tame. What I meant is, I think he can be tamed. You know, with the power of love trope.

corniest thing ive read all day but most BL do end up like this shit

Exactly

Exactly! But even though I want that to happen, I don't think it will
