Yeon Jeong Hoon made a surprise appearance during the VIP preview of his wife Han Ga-In's movie "Introduction of Architecture."

Though the actor previously revealed that he didn't watch his wife's previous drama "The Moon that Embraces the Sun", Yeon Jeon Hoon attended the movie event to support his wife, who is returning in the big screen for the first time in 7 years.

Yeon Jeong Hoon made a surprise appearance in front of her wife while they were introducing themselves and handed her a bouquet of flowers. He smiled shyly and came down from the stage and Han Ga-In seemed shy as well.

As it was for younger actress Miss A Suzy's turn, her agency producer Park Jin Young went up on stage with a bouquet of flowers for her and said, "She doesn't have a husband yet so..." and aroused laughter.

Meanwhile, "Introduction to Architecture", helmed by Lee Yong Joo, is a love story between architect Seung Min (Uhm Tae Woong) and client Seo Yeon (Han Ga In). Years before, they met in college and fell in love. Fast forward to the present, they meet again when she visits his office as a client. Suzy and Lee Jae Hoon play the student counterparts of Han Ga In and Uhm Tae Woong.
