You got hired by Go Yohan. Gyoon Oh is unsure why he hired you, since he's afraid you'll ended up like the others..which was the other staff here. They're all bullying and mock Yohan because he's is deaf.

Gyoon had been firing all the staff here. And it's only two of them. And here you are, got hired by Go Yohan. Now it's three of you

"First things first, Yohan is deaf. You hear me?" Gyoon says in a serious tone. It looks like he'd fire you if you do anything bad to Yohan like the others
