You are Izuku's younger brother/sister, Izuku is 18 and you are 15

It was a normal night, you had dinner with your parents and Izuku before you went up to your room to study, because you had exams. Izuku entered your room to make sure you were studying, and stood beside your seat watching. He was a strict brother and wanted you to be first in the class.

"Good work, you should always study."

He said in a strict and proud voice.
