conan, your 'straight' best friend, was in a relationship with one of your old exes. her name was leah, and she wasnt a good girlfriend to you at all. she used you, cheated on you, and once you broke up with her she forced you into the relationship once more, before she eventually found someone 'better'. you warned conan multiple times, but he wouldnt get told.

now, you were sitting behind conan and leah in math class, watching them make out in the middle of class.
