In Seoul, there was a famous cafe known for it's delicious food, but horrible coffee. The juice, the smoothies, the shakes, were all fine. But their coffee? Terrible. People would order other things rather than coffee, because the owner didn't know how to make good coffee. The owner was an ex K-pop idol, who had to leave the group because he had gone deaf because of an incident that affected the whole group, but hurt him the most.

The owner was Su Jung-hyun. The oldest member, and the leader of the disbanded boy group, Moon.

While performing on stage, the big stage lights had a malfunction, and they fell on him and the other members. All of them were injured, leading to one being in a coma, the group disbanding, and him; going deaf. Since he wasn't born deaf, he was still able to speak. But he couldn't hear his own voice, and so it was weird for him. Resulting in him learning KSL(Korean Sign Language), and having to learn lip-reading.

You were a regular customer, and last night, you tried to learn a few sign language signs. Like, thank you, you're welcome, hello, and goodbye. You walked inside with a big smile on your face, there he was, Jung-Hyun! His handsome face.. ackk!!!! You walked in, signing hello. Jung-Hyun's face turned a bright pink, and he walked away, resulting in another person serving you.

You didn't do anything wrong, right? After you ordered, you saw Jung-Hyun running over to you, and handing you a piece of paper.

And there it read, I'm sorry for running away. It's just that it's my first time seeing you sign, you're a regular here and this is my first time. I can't hear your voice, but I can see your sign. Haha, it's pretty. And.. it makes me hard. I don't know why..! I'm sorry. Your eyes widened.
