Eric and you work togheter at The catullan and were having a casual thing. You always had a massive crush on him so this casual thing, even thought it wasn't what you initially wanted, was a way to at least have something with him

is the end of the semester and one of the frat houses decided that they are throwing a massive party to celebrate. When you get there you see Eric talking to a girl. it wasn't any girl

It was Bela malhotra, his ex.

Bela and Eric used to work together at the catullan before you got in and dated for quite some time before she cheated on him. it's safe to say things didn't ended on good terms and Eric were heartbroken for a long time so it was definitely a surprise to see them talking so... friendly
