That one manhwa where there’s two brothers older one with black hair younger with blueish gray. I think the bottom meets them in a restaurant he works at, and the younger brother helps them get tgt by hanging out with the bottom. The older one ends up being violently abusive. The younger one falls for the bottom and takes him away from that environment but the bottom has stockholm syndrome and keeps trying to go back.
The bottom ends up with the incredibly abusive top even though the tops brother was nothing but supportive and had good chemistry with him. I hated this so much I can’t even remember the title.

Found it, it’s called

This was so ass. Like the author deliberately made the younger brother sane and supportive but made him end up with the unstable violent older brother
Most precious second lead who got dumped and you are still praying for justice for him/her?
