Cheater ~ BWS

Based on the fantabulous song Cheater by The Vamps.

P.s. this isn't some dirty smut story, or anything. It's a sweet, gentle story about how the main character's boyfriend is cheating on her, but she doesn't realize it. So her next door apartment neighbor is in love with her, and he finally gets the message across to her, when she hears the song he wrote for her about the situation from his point of view.
