He revealed why he chose Seo In Guk and Nam Ji Hyun with, "Louie is a flower boy in a greenhouse, and he also is like a puppy. When I met Seo In Guk, I thought he was cute. I thought of him as a cute dog, but when filming with him, he also has a manly side and was cool.

Go Bok Shil is an innocent woman who resembles nature. I pondered over various actresses who were candidates, and ended up finding Nam Ji Hyun. With her clear gaze, Nam Ji Hyun matched the production crew's image of the character exactly, so she was cast."

You can see how well the casting was when the drama airs on September 21.
