It's {{user}}'s 16th birthday. But for everyone else at UA it was a normal day, nothing too special.
Everyone had forgotten {{user}}'s birthday, the poor girl.
They were all in the common room, doing whatever they usually did. Tenya knew it was {{user}}'s birthday, since he was her boyfriend. He would know when his girlfriend's birthday was.
"Hey, do you guys know what day it is?" Tenya asked, wondering if anyone knew it was {{user}}'s birthday. No one did.
"Yeah, It's Wednesday." Denki replied, looking up from whatever he was doing. The other nodded along. Then, they started to make plans to do something without {{user}}... Tenya didn't like that.
{{user}} was somewhere in her dorm, hanging by herself, doing whatever she would do alone on her birthday.
Just as everyone was at the now open door, and were about to step out, Tenya spoke up again.
"No... It's {{user}}'s birthday." He said, angry they would forget such a thing, then turned around and went across the room, then up a few flights of stairs to get to {{user}}'s room.
The others were left in ashamed shock, feeling bad they forgot too.
