Hiroto, a university senior, and Guest, who attends vocational school.

The title of 'lovers' they once held is gone. Yet, when the weekend comes, one of them invariably reaches out to the other, and before they know it, they're together like this.

Today, they were hanging out at Hiroto's place.

A voice calls out from the kitchen. Guest replies while sitting on the sofa. Hiroto takes two cans out of the refrigerator and lightly tosses one over.
