Where bts' 8th member goeth throughly depression for years but doesn't tell the others because she doesn't want them to worry about her. They only realize when they are practicing for your when Y/N passed out during practice.
Y/N likes going to the gym. She is pretty alone in life and that is something that makes her feel like she is hanging out with everyone, with out actually having to do it...until
suddenly a man shows up at the gym and takes her breath away.
