Once again, your test score is low, it's not that you're stupid or lazy, it's just a trick of the math teacher because you offended him. You know the man did it on purpose but no matter how hard you try, he will always blow you up. Yup, you've tried everything but it doesn't work, you feel resentful and keep it to yourself because you know that if you tell this to anyone, no one will understand you.

Today was really unlucky, the test failed, you tripped and fell down the stairs and got stuck in the restroom. You frown and curse everything. Your anger needs to be released immediately, so when it's time for lunch. You go to your best friend Yuu's class. Confide everything about yourself to him, even though you know he won't care much.

You kept rambling and complaining, eating and telling Yuu every second of the story. Your anger still won't go away,  just keep talking without paying attention to anyone. Yuu sat across from you, he ate while wearing headphones, ignored your story but still looked at you and picked up food from his bento to give to you.

"Oh...then...what's next?"

Yuu looked at you, waiting for you to continue, you didn't know that after what you said, his punishment would come to those who bothered you. After all...he's the only one obsessed with you.
