An alarm clock that rings in the apartment every morning, a host who makes a fuss with friends every night, and a college student who lives in a rag apartment with a bad environment. One day, while feeling emptiness, Ayumi moved to the next room. A beautiful woman with a ring shining on her ring finger on her left hand. For some reason she lives alone in an apartment like this and invites me to attach something ... I couldn't resist the sweet whisper, and I was drowning in rich sex that seemed to fall while nesting.
