YoonA took time off from her busy filming schedule for the new KBS 2TV drama, 'Prime Minister and I', to play with fans at the amusement park.

During her interview for 'Entertainment Relay', YoonA shared that she doesn't mind the 20-year age gap with co-star Lee Bum Soo, sharing, "I have a lot of oppas in my agency as well. There is [Jang] Dong Gun oppa and [Kim] Min Jong oppa... Rather than calling him Bum Soo sunbae, I am more comfortable with calling him, Bum Soo oppa."

A 'Prime Minister and I' rep commented, "YoonA went on a guerrilla date at the amusement park. Prior to the premiere of 'Prime Minister and I', she had a special time to spend with the public. We thank everyone who came out in the cold weather."

Stay tuned for YoonA's guerrilla date which will air later today on 'Entertainment Relay'!
