BORDER LINE ~My Fiendish Chinese Classmate's Psychotic Infatuation~

Goody two-shoes Kaho hates bullying with a passion.
Her classmate Wang Wei is popular with teachers and classmates alike. He has always treated everyone equally and never shown any red flags. "Is Wan-kun always like that? Does he not have a care in the world?" Kaho thinks to herself. Knowing nothing about the true nature of Wang. One day, after school, she happens upon a case of bullying. "Koyama-kun!!? What's wrong? Why are you injured?" What she saw was Wang bullying one of his classmates. With her strong sense of will and beliefs, there was no way she would let such an injustice slide. But when she confronts him about it, he says: If it's his word against hers, who will everyone believe? That if she rats on him, perhaps the bullying will become EVEN WORSE. "After all, Kaho, you are despised by everyone in the class more than you think." Wang's words strike hard, and Kaho ends up being guilted into taking the place of the bullied party. Little did she know that her life would turn to hell from then on.
