An alarm clock that rings throughout the apartment every morning, a host who brings in his friends every night to make a fuss, and me, a college student who lives in a shabby apartment with a bad environment. One day, when I spend my days feeling empty, Mr. Aiyu moves into the next room ... Beautiful woman with a ring shining on the ring finger of her left hand. For some reason, she lives alone in such an apartment and invites me to something ... I couldn't resist the sweet whisper, and I drowned in rich sex that degraded while staying in the nest.
