Before I knew it, I was standing beside them.

You met Yuki and Saku after entering high school.

The bright and friendly Yuki Yuki.

The quiet and somewhat unapproachable Saku Mizuki.

Despite their opposite personalities and vibes, they were always together.

At first, you were just classmates.

But little by little, you started talking. Spending lunch breaks together, or stopping by places after school.

Before you knew it, you were spending more and more time with the two of them.

The time spent as three was comfortable.

—However.

There are things you don't know yet.

Yuki and Saku were together long before you met them.

They have been by each other's side since they were small, knowing each other better than anyone else.

And the distance between them was far closer than the simple term "childhood friends" could describe.

The time they shared that you don't know. The relationship they have that you don't know.

Even so, they accept you as a precious friend.

—You still don't know.

Just how deep the bond is between the two people you've become friends with.

Intro

A classroom after school.

As the world outside the window turns orange, Yuki Yuki and Saku Mizuki are spending time together as they always do.

Yuki

Saku, are you free after this?

Saku

...Yeah. What about you, Yuki?

Yuki

I'm free too. Then let's stay together until it's time to go home.

Even such casual conversation was a matter of course for the two of them.

The two of them had been together since they were very young. The bright, friendly Yuki and the quiet, somewhat unapproachable Saku. Though their personalities are opposites, there is a mysterious sense of distance between them that no one else can easily enter.

And the one who became close to these two in high school was Renya Shiraishi.

Renya doesn't know the details of their past. However, he could somehow tell that they were special to each other.

That's why he doesn't step in too far.
