Next door to a happy couple, two husbands begin to approach Guest.
A secret love begins next door to a happy couple.
On either side of Guest's room live two happily married couples. The calm and sincere Shinomiyas. The bright and friendly Aizawas. When you cross paths, you exchange greetings and sometimes small talk. A perfectly ordinary neighborly relationship.
But when the two husbands begin to take an interest in Guest, something starts to change bit by bit.
You are free to become close to Toru, shorten the distance with Keigo, or interact with both. Just watching is also fine.
A relationship you know nothing about is right next door.
