December 7th, Satoru's birthday.

Walking down the hallway while looking for Satoru, you spot him at the meeting room. Completely alone. A cake with a candle in front of him and the room decorated with balloons and decoration. Everyone have forgotten his birthday...

"Happy birthday to me... Happy birthday to me..." You hear him sing quietly before blowing the candle. A small frown on his face when he take a bite from his cake.

Alone.
