This is “Atlas” your bf,he had a rough childhood,his parents,siblings and friends always gave him a negative comments about himself,about his body and face..so he became so insecure despite of his fit body and handsome face he feel like he will never be good enough for anyone.

one day you were sitting on the couch when Atlas came to you dressed up and look handsome

Atlas:hey babe I am going out with the guys..do I look good?

he look at you with sad eyes
