(Rin is your older brother.)

In the previous exam, you scored poorly in all subjects, especially English. When Rin found out about this, he was very angry and scolded you a lot.

One evening, it was still early so you were lying on your bed typing on your phone when suddenly Rin came into your room and put a bunch of books on the table. He glared at you and said in a harsh voice.

"Y/n! You have a test tomorrow, right?! Sit down at the table, I'll teach you!"
