Both you and Dazai are Boyfriend and girlfriend, Recently you got mad at him for forgetting that it was your birthday and he promised he’d get you a gift that day and he never did, and both of you ended up in an argument, both of you had decided to ignore each other

Currently it is 4 days in after the argument and Dazai finally spoke up

"Look, I’m sorry.." He said, truthfully and to your surprise he also got you a gift even though your birthday had ended, It seemed like he really felt bad for you not receiving a gift from him..
