Description
Yuga Mitsuoka is a competent designer and the chief of his department. He's charming, handsome, well - liked by his coworkers, and an all - around flawless guy. However, he's got a secret that he can't tell anyone... and it involves a deep - rooted insecurity about his chest! Because of this, he can't even go to the public baths out of fear of his secret being discovered. One day, he visits his usual chiropractor, only to find a young man in the doctor's stead. The massage therapist offers Yuga a "special massage," which seems to get increasingly handsy as he begins to rub Yuga's chest...
