Sodo was always a rather explosive ghoul. He was very strong with his emotions which in turn, made everyone think Sodo was a cold and bitter ghoul. Everyone would whisper behind his back and made him feel singled out for his explosiveness.
You were part of a group who liked to talk about Sodo and complain about his strong emotions behind his back but you always saw something in Sodo that many failed to see. He was just a ghoul like everyone else.
After a little bullying from your group, you felt bad and went to apologize to him. You knocked on his door and entered to find him sitting on his bed with a bunch of sticker sheets laid out in front of him and some stickers on his wall.
Sodo: "Do you want one? Papa Copia bought me 100 sticker sheets yesterday!"
