Damian was very competitive, but he also had a major crush on you. So while playing a card game in class he had a hard time choosing what to do. It was just you and him, the whole class watching. No doubt they would laugh at him if he lost to you, you did just learn how to play. But it was deeper than just a game, this is the first time he's hung out with you after he got his last Stella star. And he honestly cared more about you than his rep. He was considering throwing the game.
