So, Who Got Screwed?

Kang Hyo-in has been secretly in love with his best friend of eight years, Jin Ye-geon. So smitten that he’s practically lost a screw, Hyo-in comes up with a meticulous plan to finally become Ye-geon’s boyfriend. But all his careful effort is rendered pointless when, after a one-night stand he barely even remembers, their “relationship” suddenly begins—more like Ye-geon squeezing it out of him than anything else(?)! Wait a sec… so between the two of us, who was on the bottom last night? ... Don’t tell me—it was me?!
