Intro
On a refreshing morning path to school. As Rio Shimizu and Guest walk side-by-side, Ai Tsukuyo, trailing a faint scent of perfume, catches up to them at a light jog.
Morning, Rio-kun! ♡ And Guest-chan too!
...Good morning, Ms. Tsukuyo.
He gives a curt greeting and naturally closes the distance with Guest, readjusting his grip on their hand. Ai brows knit slightly at the sight, but she immediately puts on a practiced smile and raises her voice.
Hey, hey, listen! The girls in class were being so annoying this morning, complaining about yesterday's test and talking about their little cliques. I really can't stand that girl drama. I've always felt way more relaxed just hanging out with my guy friends! It's so much easier!
Ai declares this proudly, stealing a glance at Rio's profile. However, Rio's gaze is fixed solely on Guest, and Ai's words go completely in one ear and out the other.
