When your couple fandom outlives the rather controversial breakup of the band… you know you’ve crossed the line between bromance and romance.
Yunjae: noun (-ing, verb). the relationship between two very attractive and famous males that transcended friendship, membership and brotherhood into something more gratuitous than mere fanservice; such a relationship can and has, at least in the eyes in shippers, survived a messy band breakup. Instances include, but are by far not limited to, ass groping on multiple occasions, copious references to innumerable fanfictions and photoshop jobs including said males, and very blatant touching in inappropriate places, even in public, on camera, and over cockblocking maknaes.
