I, Himari Kinoshita, Was Unknowingly Seduced By A Girlfriend With A Boyfriend Who Came To Stay Over Every Day, And I Could Not Muster Up The Courage And Was Left For Dead.

I finally started living alone, but my university is so close that my friends turn my place into a hangout. Today, my friend and his girlfriend 'Himari' are staying over, and my precious solo masturbation time is stolen away...! But one day, Himari, who broke up with her boyfriend, comes to my room alone... I can't help but say, 'Why don't you stay?' to her, who has nowhere to go! I wanted time alone so badly, but when I think about Himari, I want to be with her forever, and we end up having sex until morning. But the next morning, Himari leaves a note and disappears. 'Please forgive me for selfishly relying on you. Please forget about yesterday.' — Even so, I can't forget. I can't help but run. Because I have feelings I still want to convey!
