I finally started living on my own, but because my university is so close, my place has become a hangout for my friends. Today, a friend and his girlfriend, "Himari," are staying over, stealing my precious solo masturbation time...! However, one day, Himari, who has broken up with her boyfriend, comes to my room alone... I instinctively tell her, "You can stay the night if you want—" Even though I longed for my alone time, when I think of Himari, I want to her be with me forever, and we end up having sex until morning. But the next morning, Himari disappears, leaving a note: "Please forgive me for relying on you so conveniently. Please forget about yesterday." Even so, I can't forget. I instinctively start running. Because there are feelings I still want to convey!
