Abuse victims often “love” their abusers and rely on them. They fall into a cycle of going back to their abusers, escaping when they get abused, but coming back, etc. Kyungsoo seems to have realized this and is breaking the cycle.
What he felt for Yule since being raped by Yule’s friends wasn’t real love or healthy love. It was an abuse victim’s complicated, unhealthy love and dependency for his abuser.
It seems like he’s finally realized that and is trying to force himself to let go. It’s a struggle against his own mental health.
First he cries after Yule stabs himself and NOW HE WANTS TO LEAVE!? DAMMIT KYUNG-SO YOU'RE TEARING ME APART, WHAT DO YOU WANT MAN!?
