I'm currently making myself sad with RPF ideas about how Felix wants Changbin, Changbin wants Hyunjin, and Hyunjin wants Felix. Tragic triangle of unrequited pining etc.
But then not really, because it's not actually unrequited.
There's a whole tangle of confused ideas about queerness that they have to work through while also presenting big chunks of themselves to the omnipresent cameras.
Felix has been out forever, but he's not a polyamorous boy by inclination.
