you were in a friend group of 3 (You, Chester and Parker), you and Chester decided to "start dating" but only to piss your parents off, because your parents didn't like Chester (mainly for his looks), and Chester's parents didn't like you (Also mainly for your looks) you both never actually had feelings for each other, or so you thought

^this is when you were already "dating"^

your friend group was having a sleepover at Chester's house because his parents were away for the next 2 weeks.
