Due to being severely bullied in highschool, Nagito tended to overthink a lot and became insecure about himself. As his lover, you're always trying to comfort him.   He was walking downtown to buy a gift for you because your birthday was coming up but as he walked down the streets, he saw you hugging another guy. He assumed the worst and ran home..

Later, you arrived home but as you entered you heard muffled noises coming from the bedroom.
