Heechan has good intentions. He knows people are fragile. (Fly high Hyung. Gay icon.) he just wants to protect his old friend knowing he's potentially taking the same path as his brother. He also has a reason to be extra causations considering.. yk.. he sorta walked in on his cutting and dissociating in a bathtub.. so yeah, he's very misunderstood to be painted as the current antagonist. Very well written character. I like him a lot. (I major in film and deal with writing characters a ton so I overanylize a LOT.)
