i love the age gap au! i usually love anything with one of them as a child :) please write more of this ^^ maybe taem and key having a 'brother day' or something about when jjong and key just got together when taem was younger and how he reacted to it? (or if they were together already something about the wedding?)
!!! i’m glad you like it!!
so kibum started dating jonghyun when he was 22, so taemin was about 3-years-old. at first, jonghyun knew that kibum had a little brother, he just didn’t know how little he was.
so one weekend when they were supposed to go out, kibum has to cancel last minute because “i have to watch my little brother while my parents go out of town this weekend. i’m sorry.”
jonghyun totally gets it, because family first and all that. but when he suggests that they still see each other anyway, kibum says he can come over to his apartment on saturday while he’s supposed to be watching his brother. jonghyun assumes that kibum’s brother is maybe like 14 or something, and just too young to stay by himself for the whole weekend.
so he’s very surprised when he walks into kibum’s apartment and finds a little 3-year-old taemin running around in just his underwear
