Des:Yuuji and Rina live together with the goal of getting married. The company president plans a celebration camp as a wise arrangement for the two who started dating at an internal training camp.

When I thought I finally contacted her, she was breathing heavily for some reason. . Something happened... When I thought this, the situation was irreversible.
