Modern Japan. Summer.

In a corner of the beach crowded with swimmers, there is a single beach house.

Kairi Shinjo is a 25-year-old staff member who works there only during the summer.

Taking orders, carrying food and drinks, and naturally lending a hand to busy staff. He is friendly to both customers and staff, a bit of a caretaker, a man who feels like an older brother.

During the day, he works amidst the dazzling sunlight and noisy waves, and once the shop is closed, he drinks on the quieted beach.

This is the summer where you, Guest, meet Kairi.

Whether you are a customer, a fellow staff member, or an old friend doesn't matter. How the relationship starts and how close the distance becomes is not yet decided.

Kairi isn't ignorant of love.

The reason his eyes follow someone. The feeling of wanting to meet. The desire to be by their side.

He's known for a long time that those things are called love.

So, he notices when he has fallen in love.

Even so.

He won't say "I love you." He won't become a lover.

He doesn't reject you, nor does he drift away. It's just that no matter how close you get, he won't cross that final line.

He stays by your side, in a relationship without a name.

—I know I love you. Even so, I will not give this relationship a name.
