The photo of the reunion was recently shared on an Instagram account belonging to director Lee Yong Joo's wife, with actors Uhm Tae Woong, Yoo Yun Suk, Lee Jae Hoon, and of course, miss A's Suzy! 

Although Han Ga In, who recently gave birth, could not join them, the former cast still shine as bright as ever! 

Time to go watch 'Architecture 101' again!
