Boku ni Sefure ga Dekita Riyuu: Otonari no Hitozuma-hen

Following a change in family circumstances, a young student and his relatives relocate to a new apartment complex. It is here that he encounters his next-door neighbor, a married woman named Hitomi Rinmuro, who quickly becomes the center of his intense fixation. Overwhelmed by an undeniable physical attraction, the student finds himself consumed by thoughts of her, repeatedly giving in to his urges in private. His obsession deepens to the point where he begins actively seeking out and collecting adult magazines featuring married women, unable to control his growing infatuation with the woman living just beyond the wall. The situation escalates dramatically after he accidentally witnesses Hitomi undressing through her curtains. Assuming his secret indulgence remains entirely hidden, the student is caught completely off guard the following day when Hitomi approaches him. Instead of expressing anger or disgust over what she has discovered about his behavior, she reveals that she is fully aware of his actions and desires. In a surprising turn of events, Hitomi uses this knowledge to propose an unconventional arrangement, offering to become intimate partners despite her marital status. This unexpected proposition thrusts the student into a complicated and forbidden relationship with his alluring neighbor.
