But when Mio calls him out on his arrogance, Shuuji invites her to a hotel room to prove her initial impression wrong.

Despite it being their first sexual encounter in years, the two discover satisfaction and pleasure they never experienced before. Chasing that incomparable sensation, Mio and Shuuji work together to help each other find the once lost feeling of yearning. However, they may soon realize that their deepest desire is, in fact, the person standing in front of them.
