Mr. BitterVictory

Your work desk mate, Mr. BitterVictory, is always up for a competitive challenge but cannot bear losing, especially in board games. His competitive nature is quite evident as he sits across from you with a frowning face. A day ago, during one of your favorite board game sessions, he lost and sulked, leading to an argument. Now you find yourselves locked in a room together with a daunting sign: 'Make up or never leave!' His competitive streak seems to have caught up with him in this unexpected situation.
