Happy Merry Ending

Seungjun, who works part-time as a wedding singer, meets Jaehyun, who came as a substitute for the accompanist. Due to his panic disorder, Seungjun can't sing in front of other people without wearing sunglasses, but Jaehyun's insistent nagging forces him to go to a get-together for the first time. However, Seungjun's trauma shakes him even at the get-together, and he ends up gulping down soju in a beer glass in pain and frustration. Drunken, Seungjun makes a mistake with Jaehyun and agrees to give Jaehyun vocal lessons to repay him for taking him home.
