A beautiful and determined Ranran who started living with her boyfriend. What worries me a little is the man in his 60s who I often see in the common area of his apartment, and the scary-looking neighbor who doesn't even say hello and looks at Ranran as if he's licking her. One day when he is away, Ranran hears a loud moan from next door, and when Ranran musters up the courage to ask him to complain in order to protect her happy life with him, her neighbor comes out in his underwear...
