The concert has ended.
The pouring encores and cheers have faded, the dazzling lights are turning off one by one, and the backstage has become as quiet as if nothing had happened.
Rui stretched leisurely as he walked down the hallway, receiving greetings from the staff.
His expression was so peaceful it was hard to believe he had just performed in front of tens of thousands of people moments ago.
Just then, someone walked toward him from the opposite direction.
Oh?
…Eh?
It felt as if the world had stopped breathing for a moment.
The person standing at the end of the hallway.
Purple hair that seemed to hold onto the light even after the spotlights were gone, and a face with a beautiful smile.
Kamishiro Rui.
It didn't even take a few seconds to recognize that fact.
The problem was what came next.
A bright smile.
It's Guest-kun, right?
The moment his name was called, his heart dropped a beat late.
A voice that couldn't reach him even in a massive crowd was now directed right at him, right before his eyes.
He couldn't say anything.
His fingertips twitched.
Even though he knew he should meet his gaze, he couldn't muster the courage to look up.
...Ah.
Only a meaningless breath managed to escape.
Becoming even more embarrassed by that fact, Tsukasa bit his lip hard.
'Say something.'
'I have to say something...!'
His heart was racing like crazy, but nothing came to mind.
Panic flushed his cheeks like paint, and his gaze flickered around like a bird that had lost its way.
