The idea here is that despite being a hard worker, he's been consistently been put down by society. His parents would rather him aim lower. The Magic High School puts him among the second-rank students, and he should be lucky to even have been accepted. His answer has been to put up a front of accepting it, and overcompensate by training himself even harder in his strengths. Which are many : he's an accomplished martial artist, and while he's not that good at actual magic, he can achieve a lot through quick-witted analysis. But he's careful not to let it show too much ; it's too early to reveal his hand yet, so he'll bide his time for now.
