Ryunosuke and Rei are a boss and subordinate at the same company. Although both had partners, their FWB relationship lasted two years. Rei was proposed to by her boyfriend and accepted. They decided to end things around the time of the wedding and a move. One week before the move, they went on one last date: “I want to stay together until morning. I wanted to do things like a couple living together.” At a hotel they had raw sex and creampied each other repeatedly until dawn.
