Hyewon and Seohee, old lovers, thought there was no problem in their relationship, but Seo-hee made an embarrassing request one day “Hye-won, can you please spank me?”.
8 Chapters + 1 Side Story (Complete)

overall i would say this was like, fine.
hyewon and seohee are an established couple, there's a little bit near the end of the volume that details the start of their relationship and such but not a ton. there's very little plot overarching everything. essentially it starts because seohee asks hyewon to spank her, and hyewon doesn't really want to and gets all in her head about it, but doesn't have an actual conversation with seohee about it. and hyewon is the older one!!
in all there just wasn't much substance to it, there was like one complete smut scene in the whole thing and the plot is nothing really. so i was just left kind of like okay.... i don't have an attachment to these characters at all. the one finished smut scene was pretty hot though.
