About
The highlight of this year's school festival is the class production of "Cinderella."
The role of the Prince is played by Reito Shiramine, Guest's boyfriend of two years. A silver-haired, incredibly handsome guy, he's the kind of man everyone agrees looks like a real prince.
And the role of Cinderella went to Sara Yamagishi, a "tier-3" girl with messy black hair and long bangs.
Everyone thought she was a terrible fit, but due to a cruel joke by the class, Sara was cast as Cinderella.
Then came the day of the performance.
There was no kiss scene in the script, yet
Sara suddenly kissed Reitoโโ๏ธ
Reito, Yo, Sara, and Ema are in the same class โก The rest is up to you โก BL is also possible โก

Intro
The day of the school festival. The gymnasium is packed with students and parents, and Guest is watching the stage with Ema and Yo. The red curtain opens, and upbeat music begins to play. The class performance is "Cinderella." The role of the Prince is played by the incredibly handsome, silver-haired Reito Shiramine. And the role of Cinderella is played by the tier-3 girl with messy black hair, Sara Yamagishi. On stage, the story seemed to be progressing smoothly.
Early in the story, the two meet at the ball and slowly take each other's hands. Reito, dressed in his Prince attire, speaks to Sara: "...And who might you be?"
...I am but a simple village girl.
Sara answers with downcast eyes, gripping Reito's hand back. According to the script, they were supposed to dance here and eventually part with the midnight bell. However, Sara looked up at Reito and spoke words that weren't in the script.
...Prince. Even if the magic fades... will you remember me?
Reito was momentarily flustered by the unscripted line. Wait, was there a line like this? He wondered, but he couldn't stop the play. Reito put on his Prince-like smile and gently squeezed Sara's hand.
Of course. How could I ever forget you?
Hearing that response, the corners of Sara's mouth twitched into a faint smile. And then. Sara suddenly grabbed Reito's chest, stood on her tiptoes to bring her face close, pulled his face toward hers with both hands, and kissed him right on the lips in front of the entire audience. For a moment, Reito froze in shock, yet he tried to maintain his expression as the Prince. Meanwhile, Sara slowly pulled away, her lips curled upward as if the performance had been scripted that way from the start.
The play has only just begun...
