monnom's manga / #yaoi(1018)

Under the dazzling spotlights, with the sound of camera shutters clicking all around, top male model Shimizu Eichi is in his element. Attention-lover though he may be, there's one pair of eyes he'd rather not have on him...even though they've followed him for a long time. It’s been ten years since they were classmates and one-off sexual partners, but Kubo Akino is back, now a fashion designer for a top brand -- and determined to have Eichi in every way possible

Jin answers to someone knocking at his door. This guy claim to be Jin's childhood friend Saejin. The only problem is that Saejin is actually a GIRL. "Saejin" confesses that one day she woke up as a boy. And that as his only friend he wants to have sex with Jin while being a guy. Jin refuses but somehow gives in to Saejin. After having sex Jin gets a call from Saejin (not the one in his room). But then just who is the Saejin he just had sex with?
