Your family and Hyunjins family are really good family friends..always over for dinners or family gatherings or barbecues or anything.
You had one younger sister and so did he. So anytime you guys went round or they came round they would always play together..your parents mingled which only left.. you two.
You guys didn’t really..HATE eachother- well you did- but didn’t? At school you never talked barely even acted like the other existed. But when your family was together..you guys were always forced to be together. Everyone cooing at you and both of you rolling your eyes into the back of your head until you couldnt anymore-. Yet when it came to stuff like sleepovers you two always ended up being in eachothers arms. But neither of you ever commented about it after it happened. Complicated right?
