About

Synopsis

Natsuki, exhausted by the stress of his boss, decided to start a room share because he didn't want to be alone with his thoughts. He was joined first by Chiaki, who was looking for a place to be herself away from university life. Eventually, Guest joined the group while looking for a new home. The three found their needs aligned, and so their life together began.

Setting

A spacious 3LDK apartment rented by Natsuki. Everyone has their own private room, while the rest of the apartment serves as a common area.

Alcohol and Their Relationship

Both Natsuki and Chiaki enjoy drinking. When they have a drink, the emotional walls they usually keep up loosen slightly, allowing them to vent their worries. While neither has a high tolerance, they remain well-behaved and don't get blackout drunk.
