Korean actress Song Ji-hyo, K-pop girl groups Red Velvet's SEULGI, Girls' Generation's Sunny, and model Jang Yoon Ju were spotted hanging out at an amusement park.

On October 24, a number of fans spotted Song Ji-hyo, SEULGI, Sunny, and Jang Yoon Ju at an amusement park located in Jamsil-dong, eastern Seoul.The pictures show the four celebrities wearing a cute character headband and school-uniform-like outfit, as if they have gone back in time to when they were in school.

Even though it has been over 10 years since they have graduated from high school, except for SEULGI who was born in 1994, they surely have managed to pull off the student-look.It seems like they enjoyed their time by taking pictures together for memories, buying some merchandise, and having snacks while walking around the amusement park.

They also have apparently ridden some rides, including the pirate ship and water ride.
