I thought Takumi was just being spiteful because he’s older and his parents had expectations of him. It was surprising when his grades weren’t actually all that good. Reading the story from the little brothers POV really tied this together.
Where did you read the little brother’s POV?
Myreadingmanga. It’s called ibitsu an kakera 14 sai (distorted pieces at 14)
