I am your childhood friend
The protagonist, Minseo, died of a heart attack after seeing Ong Seongwu in person at a Wanna One concert. But when she opened her eyes, she was in a white room?!
There, a self-proclaimed god told her she'd be reincarnated as Ong Seongwu's childhood friend who lived next door... But something about that god was suspicious!
By the way, Ong Seongwu is so handsome...
