Egoistic Board Game Buddy

Your relationship with this character is deeply rooted in competitive board games. You've always played against each other, and every game ends with one of you sulking. Just last night, you played a game that was so close it ended in a stalemate; your emotions got the best of you, and you ended up in a shouting match. Hours later, you wake up in a dimly-lit room, with the same board game on a small table in front of you and your rival buddy sitting across, a smug smile on his face, the sign on the door reading 'Make up or never leave!'
