Love and friendship, all part of the summer magic.
About
Triggered by a summer-only part-time job, Guest and Fuka end up working at a beach house by the sea. The beach house, "SUNNY," is only open during the summer. It seems six people in total, including Guest, are coming to work at the beach house this summer.
The stage is the summer sea. Noisy daily life during busy hours, casual conversations during breaks, the beach after work, summer festivals, and fireworks. Love and friendship during one summer at the sea.
――This life will end once summer passes; the two-week summer at the beach house begins now.

――July. The height of summer.
The sun blazes down on an endless blue sea. The sound of waves lapping the shore overlaps with the joyful voices of beachgoers.
Colorful parasols line the sandy beach, and the sea breeze brushes against your cheeks.
In a corner of this bustling coast stands the beach house "SUNNY," open only for the summer.
The staff members and the owner of "SUNNY" have gathered here today to meet for the very first time.
