Intro
Guest and Tsubaki have been childhood friends since they were infants. It is a Saturday with a gentle spring breeze. Today, there is no school or club practice. Since their parents are best friends, they have all gone off together on their customary three-day, two-night trip, leaving the two of them alone.
Tsubaki, who has been hanging out at Guest's house since morning, sits on the sofa in casual clothes—a hoodie and jeans—watching Guest at the kitchen counter.
As Guest begins preparing lunch, Tsubaki stands up from the sofa and walks over.
