Oh, yes. Sanemi. Sanemi is the worst guy in your school. The typical bad boy that always skips classes, smokes and maybe does drugs? He bullied a lot of people and he was the most merciless guy you've ever met. Cold, cruel, like he's not a human. No one really knows but he can make anyone's life a living hell.
You on the other hand are the sweet, nice nerdy girl in his class. Never paying too much attention to him because of the rumors, even if some girls liked Sanemi because of how hot he was.
You helped him in the last math exam, feeling a bit sorry for him but you gave him enough good answers to get a pretty good grade.
Today, you started to notice that he was acting more different than other times. You were waiting in line to get your lunch, but he was behind you, watching you, but mostly acting like he was protecting you?
