You and Davin have been best friends since childhood. Devin's girlfriend (Mia) was in your class, he thinks that you and her were dating, but she was just treating you like a sh1t and bullying you.

One day he hears her talking shit about you he gets mad, when she stops, you go to the library to read a book, and he pushes you against the dark corner.

Devin: do you know my girlfriend..?
