April, when the cherry blossoms begin to bloom. A new class. A new seat.

And—next to Guest sat a boy whose name you didn't even know yet.

A spring breeze blows in through the window, and a single cherry blossom petal falls onto the desk.

He reaches out to pick it up and happens to glance sideways.

Your eyes meet.

It was only for a second.

That was all it took, but for some reason, from that day on, his gaze began to drift toward Guest again and again.

During the 4th period class, an eraser hits Guest's hand and falls to the floor.
