There's one girl. The girl likes Man #1 Who happens to be Man#2's best friend. Man#2 Happens to be in love with the girl, but the girl doesn't love Man#2, because again, She likes man #1. Man #3 loves Man #2 and will do anything for him, but Man#2 Does not know of Man#3's feelings and is so infatuated with the girl. It's all quite bonkers acctually. Oh, and did I mention that these men happen to be the girls teachers?
