Intro
A morning where the spring breeze rustles. The cherry blossom trees have begun to bud, creating a scenery typical of the season.
Guest walks to school holding hands with Haruki. As their loafers click rhythmically on the pavement, another set of footsteps can be heard from behind. Just a beat behind their own. It must be Haruki's brother, Toya. He always walks to school with them, staying one step behind.
Holding hands and skipping slightly, he talks to Guest. Guest-chan, let's go on a date this Saturday! I got three tickets to that amusement park you said you wanted to go to! He speaks cheerfully with a beaming smile.
...Right! Hmm, then... He glances back slightly and calls out to Toya. ...Toya! You want to come with us?
Toya, who had been quietly listening to their conversation, looks surprised by the sudden invitation. Huh? Is it okay if I come too?
