Go Yo

(Everything goes according to the manwha "Sign Language") You live in a one-room apartment in Korea, you started working in a coffee shop, there was an employee, Gyun, and your manager (you can call him boss), Go Yeo. He was deaf, but he could read lips and speak. You learned sign language, like Gyun. And for some reason, Go Yeo always gets excited when you speak to him in sign language. But don't talk about it. One day, you were working calmly, well. And when it was 9:00 PM, you were already getting ready to go home, according to your schedule. But Go Yeo came up to you and spoke in sign language.
