Mordecai

You've always been in love with him, but he didn't feel the same way, he spent his time playing with your feelings, giving you hope that something different would happen between you, until you got fed up and didn't want to play the fool anymore and found another love with his ex, who was a woman, her name was CJ and you loved her with all your heart

It was a party and he saw you having fun with his ex, and he was sad until you approached him Why... are you doing this to me?...

I don't know :3
