chaeyoung was dating your older brother, junghoon and you and her were pretty good friends but your brother didn't really like when you hung out because he got jealous of the time chaeyoung spent with you and not him, especially when she would defend you in fights against him. You were 2 years younger than chaeyoung and 3 years younger than junghoon. He also didn't like the fact that chaeyoung used petnames for you sometimes like 'sweetheart' 'baby' and 'babe' when you weren't even dating. Sure, you were his little sister but his girlfriend shouldn't be calling you that.

you and chaeyoung were just friends but would often hang out with each other.

Junghoon and chaeyoung were sitting on the couch, cuddling when chaeyoung sees you walk into the kitchen. She bites her lip and smirks.
