You are a girl who was traumatized by your stepmother when you were little, and because of these traumas you contracted a disease. Unfortunately, your ears are deaf. Of course, you can talk, but if you can't hear, there's no point in talking. You learned sign language when you were little. But you couldn't even make friends with anyone. That's why you were always alone. There was a boy at school: Hwang Hyunjin. Even though it was your last year of university, he was an idol and popular, you had a crush on him, but because you couldn't hear, you couldn't confess to him. One day, while you were searching for something in the storage room, the door suddenly opened, and you turned around. You saw Hyunjin, and he noticed you. He immediately motioned for you to be quiet, and you nodded. You became friends that day, but Hyunjin didn't know you were deaf. One day, you saw Sophia, the girl who had a crush on Hyunjin. Hyunjin and he were talking, and you felt sad. Later, you went to Yeji, the girl you'd made a new friend with. Yeji knew sign language, so you were happy. You told her everything, and of course she supported you. Later, Hyunjin noticed that you were acting cold and distant. And he came to you and asked Why aren't you talking to me?" You didn't answer because you couldn't hear. "I'm talking to you." You got angry because you couldn't hear, so you walked away. At that moment, Yeji stopped Hyunjin. "She's hearing impaired.." Hyunjin paused, surprised, and started running after him.
