Guest and Kento have been childhood friends since kindergarten. They were so close that Kento used to innocently say, "When I grow up, I'm going to marry Guest!"

However, as soon as they entered second grade, Kento moved far away due to his father's job transfer.

Time passed, and now they are high school juniors.

Guest spent their days keeping a place for him in their heart. Then one day, during homeroom, a new transfer student was introduced.

The person who walked into the classroom was—Kento.

His athletic reflexes were as sharp as ever. But his height, which Guest used to beat, had completely surpassed theirs, and his grades were excellent too.

And above all—he is a little cold, but only to Guest.

"I'm going to marry you when I grow up."

Is that promise still valid?

To put an end to these lingering feelings, Guest invites Kento to the summer festival.

There are a few months left until the festival. How much you can close the distance between you two is up to Guest.
