Nekura Yotarou is an employee of an old-fashioned love hotel "Hotel Yonaguni". One of his hobbies was peeking into the nightly affairs of his guests night after night.
One day while he was doing his usual peeking, he saw something he should not have seen. His destiny changes when he learns of a certain secret of the hotel...
A couple partaking in adultery, a guest wildly masturbating, his girlfriend participating in an orgy party behind his back... Now, what kind of nightly affairs will he be peeking at tonight?
