According to SBS, the crew kicked off the drama's official filming by recording a reception scene at the 63 Building in Yeouido, Seoul on July 15th.

Senior co-stars like Park Young Kyu, Cha Hwa Yeon, Kim Ha Gyun, and many others all praised, "Jaejoong is an actor who will attain greatness. Let's all support him so that he can do even better." Staff members who had been watching Jaejoong interact with Ji Sung for their script also complimented, "They're truly a great senior and junior." Producers of the drama added, "Before filming began, Jaejoong made sure to check over not only his script, but his outfit and make-up as thoroughly as possible.  Although it's his first time acting, he is as passionate as any other actor out there."
