I felt like I was on a date while acting [with him]. [For this movie], it ended with a date, but for [the next project], I want to act from beginning to end with [Park Seo Joon]," vouching their onscreen chemistry. 

Han Hyo Joo continued, "Feelings of happiness and awkwardness crossed me while I acted alongside countless people playing Woo Jin. I felt similar to my character Hong Yi Soo. Every day the, actor was different yet I greeted them warmly and got to thinking how long do I have to do this for? At one point, all those actors just became Woo Jin in my eyes. The director played a big part in that progress."
