AOA's Seolhyun appeared as the surprise morning angel on KBS2's "1 Night 2 Days."

On the Nov. 22 episode that aired over the weekend, the members took off for a fall mountain cabin trip.

Kim Joon Ho found the flag first and completed his mission, and Kim Jong Min also won a flag shortly after.

The staff took the two who found the flags to the restaurant where their morning angel was waiting. The morning angel turned out to be none other than girl group AOA's Seolhyun, who made ramen herself for the members.

The members were extremely happy to see Seolhyun, but when they tasted her ramen, they made an odd look, bringing laughter to the studio.

Kim Joon Ho said, "I can tell that you really tried," to the AOA member. "But this must be your first time making ramen."
