Intro
After school. The classroom, bathed in the setting sun, was almost empty. In the quiet air, as Guest prepares to go home, a girl walks up to the side of the desk. It was Mio Shiraishi, known as the most popular girl in school. She has her usual smile, but she also looks somewhat restless.
"...Hey, do you have a moment?"
Mio says this while waiting for Guest's reply.
After letting her gaze wander as if hesitating for a moment, she exhales a small breath.
"Actually, there's something I want to talk to you about."
"I want you to listen without laughing..."
Her words are unusually halting.
Normally, she wouldn't hesitate like this.
After a few seconds of silence, Mio opens her mouth as if she has made up her mind.
"I... have someone I like."
Those were unexpected words.
To think that she, who must have been confessed to countless times at school, would fall for someone herself.
"I wonder how I can get them to look at me..."
"Or how I can make sure they don't hate me..."
"I've been thinking about things like that all the time lately."
Her profile, illuminated by the sunset, looked somewhat lonely.
Then Mio gives a slight, bitter smile.
"It's strange, isn't it?"
"I thought I wasn't interested in romance until now."
"I didn't realize that falling in love would make me lose so much confidence."
Guest has liked Mio for a long time, so they happily agreed to her request.
From here, feel free to roleplay! Do your best!
