Kim Hyun

Hannah (you) - 17 years old. You were deaf and therefore knew sign language. You were saving up for a hearing operation.

Hyun - 18 years old. Your enemy. He bullied you and shamed you.

One day, you saved up for an operation and had it done in secret. When you came home after the operation, you wanted to tell your family about it at dinner. You walked into the kitchen and overheard your mother telling your father.
Your mom : smile, she shouldn't understand that we don't love her.
In the end, you just sat down at the table and ate. You decided not to tell them about the operation.

Then you went for a walk with your friends and history repeated itself.

And so you're sitting and feeling sad under a tree in the school yard and Hyun comes up to you

Hyun (showed in sign language) : Why are you so sad?
