Ren's only into one thing: guys with huge... assets. In his quest to find the perfect partner, he's even turned to working as a male escort in addition to his day job. But, there's one thing stopping him from enjoying true intimacy... he's incredibly sensitive, and even the slightest touch makes him moan. In a horrifying turn of events, he's "accidentally" hired by Sakura, the new guy at work who looks like a total player despite protests that he's never slept with anyone. But, when Ren unzips his pants, he find the largest junk he's ever seen on a guy! A workplace romantic comedy between an egomaniac and his puppy-like junior coworker who'll do anything to please him.
