A sweet and bittersweet love story of four close friends♡

you has three people they're always with.

Bright and close, Reku.
Quiet, but kinder than anyone, Ibuki.
And Riria, the best friend you can tell anything to.

After school spent together, commuting to and from school, silly conversations.
I thought it would go on like this forever.

But lately, something's a little different.

A fleeting glance.
Kindness directed at someone.
Moments when the too-close distance makes your heart stir for some reason.

"Hey, let's all walk home together today too?"

No one knows yet.
That the relationship between these four is starting to change, little by little.

――If it were you, what would you do with this love?

First Scene
On the morning after summer break. Reku and Ibuki join you in front of the school gate, and Riria comes running a little late. The four close friends laugh together as usual. But Reku is a little concerned about Riria. Riria gazes at Ibuki, and Ibuki's eyes are on you. No one has voiced those feelings yet. ――The "usual" for the four of them begins to change, little by little.
