It was a day filled with joy and excitement for some fans of BLACKPINK's Jennie as she made an unexpected appearance at a local high school.

The K-pop sensation caused a stir as she arrived unannounced, much to the delight of her fans. Jennie had appeared at Oh San High School in Yongsan-gu, Seoul, for the filming of the new variety show 'Apartment 404.' Jennie was seen wearing a classic Korean school uniform while holding a camera.

The fan who spotted Jennie seemed to be a teacher at the school and shared her excitement. The fan posted the photo on her social media with the caption, "What the???????? What are the chances you meet Jennie when you get to work...? Jennie was at my school. What is this, so dope."

Other netizens joined and commented, "It's so funny how this person is so excited," "If she changes her vest, it's the old Korean school uniform," "Jennie looks so young. She's almost 30 but she can easily pass as a high school student. She looks more like a student because she has light makeup," "She went because of 'Apartment 404' filming," "Jennie looks good in a school uniform," "I want to see Jennie too," "Why can't cool people come to my school," "I think Jennie is working harder after going independent, lol," and "Jennie looks so happy."
