Some lucky middle school students were in for a special treat, as Seventeen made a surprise visit earlier this month for a hidden camera event!
On the latest episode in a series by 'Dingo', Seventeen went undercover to surprise the students at Cheonan Seo Girl's Middle School on camera.
Members Junghan, Hoshi, and The8's missions were to pose as cameramen in front of the students during yoga sessions, without getting caught.
With their faces fully covered, the trio went inside the gymnasium where the girls were dressed in their pink gym uniforms. The members danced to Sunmi's "Gashina", still undercover as they tried to give out hints to the oblivious classmates.
