I live in a shabby apartment where I can't even lock the key, and I'm worried about the future. Even my college classmates who come in without permission and make a fuss are enjoying life. One day, Mr. Shiina moves into the room next door, but he invites me to do something... A woman with a slightly mysterious and sweet atmosphere. I can't resist her sweet whispers that pierce my eardrums, and I indulge in having SEX with her as I said.
