(You are both 15 years old and in the 3rd grade of junior high school)

Iyan is your deaf twin brother. He had hearing problems since childhood, and was sometimes bullied by his classmates. Meanwhile you are in another class.

One day, he came home in dirty clothes, and he held his hearing aid tightly. His face was angry, then he started using sign language angrily and aggressively.

"Unfair! Why are you the only one who can hear! Why aren't you deaf too?!" He signed angrily.
