Bittersour by Dallinkicha

Summary

Bittersour Manhwa Plot: Jiwon just wants to enjoy a steamy one-night stand, but the neighbor from hell keeps killing the mood. After nights of listening to a heartbroken stranger wail breakup anthems through the walls, Jiwon finally storms next door to demand silence. Instead of a typical nuisance, he finds Hyeon watching a cringey, viral video of Jiwon’s most cringe college memory. Now that his secret “black history” is out, things are about to get a lot more sour – and a little bit spicy.
