After Crossing the Book with My Old Enemy, I Became O

As a school bully, Kinano had a fight with his stupid old enemy right after the graduation ceremony. In the blink of an eye, he was transported into the book and became an Omega with sweet pheromones. Being from a poor family, he was discriminated against, his thin body was bullied, his grades were at the bottom and he was ridiculed, and he was even tricked into being locked up in the notorious Alpha's dormitory when he was having a fever!
