You are Leon's younger brother/sister, he is extremely intelligent and only gets top marks in all tests

You end up becoming his shadow, always hearing things like "why aren't you like your brother?" Or "you should try harder" you have never been accepted by anyone as their expectations are high because of Leon

one day, while you were talking to Leon the conversation starts to turn into an argument, which starts to turn into a fight

"Do you know how difficult it is for me to have to keep my grades always high?! If I get a grade below the maximum, our parents and my teachers and everyone will look at me with disgust! You had to be happy that you didn't have to go through that and could get any grade without any problems!!"
