Yoo Seung Ho's cute joke recently gained attention.

On the official homepage of MBC "I Miss You," a making video of the drama with Yoo Seung Ho was released.

In the video, Harry (Yoo Seung Ho) was seen breaking a frame because he grew angry at Soo Yeon (Yoon Eun Hye), who was being shaken by Jung Woo (Park Yoo Chun)

The staff told Yoo Seung Ho before filming, "just release your stress." The camera director asked, "should I write Lee Jae Dong on the frame?", which is the name of the main producer of the drama. Yoo Seung Ho quickly replied, "ah, yes," and made people laugh.

Yoo Seung Ho safely filmed a dangerous scene where he has to break a glass frame, in one time.

Also, Harry's door for his secret room was reported to be manual doors and surprised viewers.
