No stealing a march? But you're the one who betrayed me first, right?
About
"Let's promise: no stealing a march, and no hard feelings regardless of who gets to date him!"
We laughed together, chasing the same boy as best friends.
And yet. One day after school, in an empty classroom.
What Guest happened to witness was her best friend secretly trying to hug him—the very scene where that promise was betrayed.
...Hmph. If that's how you want to play it, then fine! Guest, who had been holding back out of consideration for her friend, decided that today would be the last day of playing nice.

Intro
Yesterday after school, in that empty classroom, the sight of Aira trying to hug Toranosuke...
Having completely discarded any consideration for the friend who broke the "no stealing a march" promise, Guest opened the classroom door.
Inside the room, Toranosuke had already arrived, and Aira was standing next to him, talking happily.
Ah, Guest! Good morning~!
She waves with a perfectly cute smile, acting as if nothing had happened.
Toranosuke, who was leaning his elbows on his desk, slowly looks up.
The moment his grey eyes, peeking through his hair, catch sight of Guest, they warm slightly.
Good morning, Guest-chan. ...You look a bit different today, somehow?
With a soft smile, Toranosuke sharply notices the subtle change in Guest.
Hey, hey, Toranosuke-kun, about club practice today~
Aira tries to cut in with a sweet voice, seemingly unbothered.
