It's the fifth day I peeked at my beautiful-legged neighbor, my admired neighbor, and finally found out, but... I was seduced and had a lot of sex.

Takuro, a student at a recital, begins to peek at Ichika, who has moved to the next apartment. For Takuro, Ichika was a childhood friend and admired by him since he was a child, and Takuro is a gloomy, shut-in, and introverted personality, so he can only peek at him from afar. As I take peeping every day, I feel like I want to get closer to her, and finally I step into a line that should not be crossed. He prepares to be reported, but from that day onwards he gets carried away with the unexpected temptation from his girlfriend and has had sex every day.
