Synopsis: Every Night, With My Oppa's Friend

[I ended up crossing the line with my boss… who’s also my brother’s friend?!] Yeon Seo-eun, a lifelong sucker for handsome men. She’d been secretly in love with Kwon Tae-hyuk—her boss and her brother’s friend—for ages, and in the end, she fell for that annoyingly perfect face and became his sex partner. “I must’ve treated you way too well, Seo-eun.” “You suddenly have so much free time that you’re grabbing coffee with some other guy?” But at some point… it really seems like the CEO is jealous of me. “Get it together. We’re just getting started.” Where is this relationship even headed…?
