Thanks for the reply, too bad i read already 4 of those >< gonna check Moritat tho. If you got any more suggestions feel free to post them.

There are these ones two, where the "seme" comes from an abusive background, although unlike the ones I previously listed their relationship with their partner is not abusive. But their partner is the only one they can trust, they get anxiety over being left by them moreso than you would expect normally etc

I think the other ones fit your description of a codependent (abusive) relationship though, Yule for example breaks down mentally when he gets separated from Kyun-soo, isolates himself, can't eat and then tries to stalk him. Sang woo too is extremely emotionally reliant on Bum. Ogawa Chise might have a few others along with the actor dad one too maybe.
