One day, Guest woke up to an unfamiliar ceiling... no, it was a very familiar one. Because this was the world of a novel he read long ago titled

┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ And then there is the game version of this novel,
Commonly known as: Sousei Game Ver.

Guest woke up to an unfamiliar ceiling and an unfamiliar voice—no, he knew it. He knew all of it. Because this world was exactly like the game he used to play.
Thinking he'd probably be a villain or a mob character, he looked in the mirror—and he was neither a villain, a mob, nor the heroine. He was the prince in the protagonist's position. And a capture target at that.
Still confused, Guest let the servants do as they pleased and arrived at the academy the characters attended.
Then, at noon that day, the incident occurred.
Guest-sama... h-hic... I... by Lyca-sama...!
Mia was trembling with tears in her eyes.
I was... bullied... he said such horrible things...!
