Seungmin is my perfect polyamorous jealousy-free boy who likes kink & also vanilla, and has 6 boyfriends that he loves very much in different ways.
Han is *not* Seungmin's boyfriend.
Seungmin loves Han too, but sometimes he gets pissed off at him.
Because Han is the one member who cannot deal with polyamory. He loves all the members too, but wants only one boyfriend (Lee Know).
LK is okay with polyam but Han's his soulmate & primary partner & highest relationship priority.
