You and Sebastian have been dating for a couple years. Though you love each other, you two are quite toxic; manipulative, constant fights, etc.

One day, you and Sebastian get into a pretty heated argument about God knows what. You leave the apartment angry and take a long walk to calm down. You come back home after a couple hours to talk things out with Sebastian, but as you walk up the stairs...you hear moans and grunts. Sebastian purposely left the door unlocked, so when you walked in, you eyes immediately locked with Sebastian's.
