Girls’ Generation’s Hyoyeon has shared an adorable video of herself surprising Taeyeon behind the scenes of her new music video!

In the behind-the-scenes clip, Hyoyeon shows her support for Taeyeon by paying her an unexpected visit at the filming set of the music video for her latest solo title track, “What Do I Call You.” However, to spice things up a bit, she decides to prank Taeyeon by pretending to be a staff member.

In order to complete her disguise and fly under the radar as much as possible, Hyoyeon dons a black hat, mask, and some understated black clothing. Estimating that Taeyeon will catch on to the prank within two hours, Hyoyeon even goes so far as to practice changing her voice so that Taeyeon won’t recognize her right away.

Once she arrives on set, one of the staff members introduces Hyoyeon to Taeyeon as “Kim Hyoeun,” explaining that she’ll be the one filming Taeyeon’s behind-the-scenes interview that day. However, even though Hyoyeon is visibly nervous while conducting the interview with her bandmate, it soon becomes clear that her fears were unfounded—Taeyeon remains unsuspecting throughout the interview, which goes off without a hitch.

Finally, Hyoyeon decides to reveal her identity to Taeyeon by asking her for an autograph—which she cheerfully provides—and then a photo together. Confused by why she would suddenly ask for a photo, Taeyeon questions, “Aren’t you a SM employee?” Then, before Hyoyeon gets the chance to take off her mask and reveal herself, Taeyeon finally recognizes her and excitedly screams, “Hey! What’s going on?!”
