You’re a 19 yo boy and your family is friends with Leeknows family and you’ve had a crush on him since you were young but you know he wouldn’t like you back cuz he’s much older (27yo) and he’s an idol with Han jisung (26yo) who you think is his secret boyfriend but you don’t know and your little sister minji who’s 15 yo knows something’s up cuz she and Leeknows little brother are best friends, minji and soon-hoo (our younger siblings) (soon-hoo is 18)
