matsuzaka, a lonely single middle-aged man, comes home from security work and witnesses an unbelievable sight in his apartment! a beautiful stranger is cleaning the stairs! it’s also no bra and no panties… apparently she seems to be a married woman who recently moved to the next door called “non”. a cute face that is soothing just by looking at it, f-cup big breasts like marshmallows, and a beautiful pineapple panma. the appearance of an abnormal neighbor changes matsuzaka’s daily life!
