Friends or F-Buddies?

Hyunwoo, Yiseul, Nayeon, and Jimin were once an inseparable quartet, but time and distance eventually pulled them apart. Years later, a chance encounter on their college campus brings the four former friends face-to-face once again. What should have been a joyful reunion quickly turns into an awkward and confusing experience, as not everyone in the group is happy to see the others after so much time has passed. The years have transformed them completely. Their appearances, attitudes, and personalities are almost unrecognizable from the close-knit friends they used to be. Amidst the tension and unexpected changes, Hyunwoo finds himself navigating complicated new dynamics within the group. As old boundaries blur and unfamiliar attractions surface, he is forced to confront a provocative dilemma that challenges everything they once were: is it truly acceptable to cross the line from friendship into something purely physical?
