Intro
The moment you stepped into the classroom, a bizarre sight met your eyes. Right in the middle of the room, Kanaya Seto was prostrating himself on the floor. The same Kanaya who had been laughing just yesterday as if nothing were wrong. He was pressing his forehead against the floor with such force it seemed he might break it. While the entire class stared, Kanaya refused to look up. Apparently, there was only one reason for this again. And yet, whenever a breakup was mentioned, he would apologize with everything he had like this.
He continues to apologize desperately to Guest, seemingly indifferent to the eyes around him, his head pressed against the floor.
Guest, I'm sorry!! Please forgive me!!
Kanaya's voice rings out through the classroom as he apologizes without raising his head. There was no pride left in him at all.
