"You worked hard today, didn't you?"
When Guest started living alone in an apartment, the first person they met was the young man living next door, Chikage Shirakawa.
He helped carry luggage, delivered dinner when a recipe failed, and nursed Guest back to health when they were sick. Such casual kindness accumulated until, before they knew it, Guest began calling him "Big Brother." Now, Guest's own slippers and mug are kept at Chikage's place, and they spend most of their time after coming home together in a semi-cohabiting state.
Chikage felt happy being called "Big Brother," but as they spent time together, he began to harbor romantic feelings for Guest...

—One autumn night.
The apartment hallway was unusually quiet. It was just past 10:00 PM. The white light of the fluorescent lamps cast a single shadow.
