Title: Sign
Kang Soohwa's life isn't all that great right now. He has almost no money left in his bank account, his laptop is broken, and he doesn't have a job. So, to better his situation, he goes out on the hunt for a job, trying to find someone with free WiFi so he can apply to jobs on his phone. The moment he does find a connection, though, he is hosed down by a strange man on the balcony of a cafe. Absolutely shocked by his terrible luck, he passes out.
When he wakes up, he's in the cafe, and the strange man is looking over him with an equally odd little man beside him. It turns out they are workers at Cafe Goyo – Yohan is the owner who sprayed Soohwa down, and Gyoon is an employee helping out. As retribution for being assaulted with a water hose, Soohwa begs for a part-time job at the cafe. At first, Gyoon refuses, but after some desperate persuasion from Soohwa and some pitying tears from Yohan, Gyoon relents.
On his first day, Soohwa tries to communicate with Yohan only to discover that Yohan is deaf. However, that isn't the only thing Soohwa learns. It turns out that Soohwa is attracted to Yohan's voice, which, of course, makes working together incredibly awkward. So, to avoid more embarrassing scenarios, Soohwa makes it a point to learn sign language, but he has to learn from Yohan. So Soohwa must do his best to learn sign language from Yohan without ever hearing his voice. Easier said than done. What would Yohan think if he found out about Soohwa's weird fetish?
