A trash middle-aged man who passes by his side confines a female college student in his own room and turns it into a sex toy.

"This is Eimi, who has moved next to me. I hope you will continue to support me from now on." It felt like the time had stopped. My heart was taken away at a glance by the girl that appeared in front of me. I thought there was no point in living... that's how I felt. I found a reason to live. I want to have sex with my girlfriend...I want to have sex...I want to have sex... That's right, you should just lock yourself up in your own room... Wait, Eimi.
