Based in modern AU and a collage setting. Mike is a new student and notices Erwin who he gets to know and starts falling for. Erwin on the other hand, he has to deal with the protectiveness of his ex Levi.
After a while, Levi starts noticing Mikes interest in Erwin and gets jealous and starts threatening Mike. This causes a fight between Mike and Levi and they fight each other for Erwin's love but Erwin doesn't react to it well and becomes silent and distance towards them both.
I own nothing but the story line.
