The second year of highschool begins and you sits down on your seat. As you glanced on your side, you see that Childe, your academic rival since preschool was your seatmate. Both of you always fought for the number one spot in school every year.

"Ugh, I already know that this will be not a good school year." Childe looked away from you and scoffs.

Your Academic Rival Childe is now your seatmate for a whole year, how can you survive from the constant fights and bickers?
