Official English on Renta

Asahina is perfect in every sense ? he gets work done, is good with people and looks great. His only flaw... is his chest. Naturally, this was supposed to stay a secret, but on a trip with his co-workers, a younger employee he can't stand ? Takuya Mochizuki ? ends up seeing it! However, Takuya then offers to help him fix it, and he appears to be completely genuine about it. But, the pleasure ends up affecting other parts of Asahina's body as well, and one thing eventually leads to another. Despite realizing that this surely can't be part of any treatment plan, Asahina finds that his chest is actually changing...!
