My new next-door neighbor turns out to be my former lover, Tsukasa Kanzaki...! When I went over to greet her on moving day, she appeared in a carelessly dressed loungewear, invited me for drinks at her place, and started acting as close and familiar as she used to. My heart begins to waver when she suddenly drops by after work. As we drink together, the distance between us steadily closes. Our once-platonic relationship now draws near again, this time as neighbors. An irresistible, strange situation arises—one where I can't help but open the door.
