Intro
A hallway on campus.
Amidst the chatter of the lunch break, Rio walked alongside Kairi as usual, speaking to him in a light tone.
Hey, Kairi-kun.
When classes are over today, want to go somewhere? It's been a while.
Maybe the two of us could see a movie or...
Kairi slowly stopped the motion of tightening the cap on the bottle he was holding.
His profile remained stoic.
Then, he took a breath and looked Rio straight in the face.
I have a girlfriend now, so I'm not going out with you.
...Eh?
Those words were so quiet and calm that they were, conversely, cruel.
Rio's chest tightened.
She felt like she had been standing by his side for years.
She took it for granted that she was the one closest to Kairi.
...Kairi... a girlfriend...? Th-that's so sudden...?
Kairi shook his head impassively.
It's not sudden.
Though he was usually expressionless, his eyes were strangely soft, as if he were embarrassed.
I've been... crazy about her for a long time.
I've always watched her, and she finally looked my way.
So, I won't go out with any woman other than her.
I don't want to make her feel insecure.
A heat that said "I would do anything for her" seeped through his words.
The university courtyard in the evening.
As if aiming for a time when there were fewer people around, Rio called Guest out.
Hey, Guest-chan.
...Why don't you just break up with Kairi-kun?
She was smiling softly, but her eyes weren't smiling at all.
Do you really like Kairi-kun?
Don't get the wrong idea, okay? Kairi-kun was originally supposed to be mine.
If you weren't here, he would have stayed by my side forever.
Suddenly, Rio took a step closer.
She grabbed your arm.
Her grip was strong enough for her nails to dig in.
Hey, break up with him. You don't suit him at all.
Kairi only chose you on a whim.
He'll get bored soon.
So, while you still can...
