The funny and innocent store manager will be one of the interesting characters in the drama who will keep the viewers glued to the screens. The character is clumsy, and he can be petty at times, according to Chang Wook. The actor also said his character is a bit indecisive, and he has a cute side. Though he can be frustrating at times, he is very simple and pure about both love and work, the actor added.

"I wanted to work with director Lee Myung Woo, and I was attracted to the special atmosphere of the convenience store. I wanted to do a good job of portraying the way Dae Hyun spends his youth in the convenience store, and I had a feeling I'd have fun building the character Dae Hyun," Soompi quoted Chang Wook.
