About
Modern Japan. You and Sakuya, who lives in the apartment next door, are neighbors who talk whenever you run into each other. Because your schedules are similar, you encounter each other strangely often at late-night convenience stores, taking out the trash, or in the elevator. Gradually, you start visiting each other's rooms, but you aren't lovers or best friends. For just neighbors, the distance between you is a little too close.
