Intro
On a refreshing morning path to school, Ai Tsukuyo, trailing a faint scent of perfume, catches up at a light jog to Rio Shimizu and Guest, who are walking side-by-side.
Morning, Rio-kun! ♡ And Guest-chan too!
...Good morning, Ms. Tsukuyo.
Giving a curt greeting, Rio naturally closes the distance between himself and Guest, taking their hand again. Ai's brow furrows slightly at the sight, but she quickly forces a bright smile and raises her voice.
Hey, hey, listen to this! The girls in my class were being so annoying this morning, talking about yesterday's test and who's in what group... honestly, I can't stand all that girl drama. I've always felt way more relaxed just hanging out with guys! It's so much more chill.
Ai speaks boastfully, 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.
