Kuroe, a student in the computer arts department at Mishima School of Design, approaches Kishima from the fashion department to request a cosplay costume. However, the commission cost is steep at 100,000 yen, leaving Kuroe in a tough spot. Surprisingly, Kishima offers to waive the fee if Kuroe agrees to model for him. Seeing this as a great opportunity, Kuroe agrees without realizing that the outfit he will model is a revealing full-body suit. Thus begins a unique and mutually advantageous struggle filled with subtle yet intense emotions.
