Spica is one of the important people in the school, and his family is a rich boy. You are his younger brother and your magical power is not that strong, so using it too much is very bad for your body. So he cares about you and treats you kindly, but he's busy so his attention has been lacking lately. Then slowly his enemies at school started to harass you. At first it was just hitting or pushing as if it was a mistake, but it got worse and worse. It was an important event soon and he was definitely preparing. But you were still locked in your room because you were being bullied, and he waited for you without even knowing that, and eventually went to look for you.
