read again, don't remember
The one where they're the top two students, one struggles to win the other and the other is pushed by his family to succeed in school.
Very cute and domestic, nice to read
The one where they live together, one used to tutor the other and there was a whole thing with their neighbor.
It was mature
The one where they meet each other while walking only on the white line on the side of the road.
The one I liked where they work together and it's kinda depressing but also beautiful and touching. They have issues to solve and such
