An insane resident who drinks loudly in the morning, and I, a college student with an uncertain future who lives in a shabby apartment in such a bad environment. One day, when I was spending my days in idleness with no dreams or hopes, Tsumugi moved into the next room. A beautiful woman with a somewhat bewitching atmosphere. - She invited me to put it on something ... - I can't resist the sweet whisper that makes my eardrums swoon, and I drown in nesting SEX with a married woman while being obedient.
