An au wherein Rik and Woong is fake dating while Gyub is Woong's brother that is head over heels for Rik and was dealing with his broken heart because he doesn't want no commotion and he supports his brother but then, Rik falls for Gyub and was wondering why Gyub is avoiding him like a plague.

I don't know, I just think Gyub being jealous is cute and Rik missing Gyub and having no idea how to tell him that he's fake dating his brother for the fame would make him stutter cutely.
