From its very start, the 'Naughty' MV is set against the seawater pool of Baegot Hanul Park. The opening scene, which sees Irene and Seulgi pass each other with the park's distinctive blue seawater pool and the high-rise skyline of Baegot New Town as the backdrop, serves as the MV's memorable introduction.

Just like the lyrics, 'Slowly closing the distance between us / It feels like I can touch you / But you run away again, far away,' this park encapsulates the push-and-pull dynamic of their relationship, where they are drawn to each other yet constantly slip away. This particular scene garnered significant attention also due to its striking backdrop. In 2020, with overseas filming halted due to COVID-19, SM Entertainment chose this seawater park in Siheung, Gyeonggi Province, as an alternative, prompting widespread reactions of "Isn't this overseas?"

The choreography also perfectly complemented the ambiance of this location. 'Naughty' features tutting-based hand choreography, characterized by intricate, high-difficulty movements that meticulously utilize each finger. The twin choreography, performed by the duo in perfect mirror-like synchronization, was so impeccably executed that it was dubbed 'shockingly difficult' at the time. Fans even meticulously paused and analyzed every single hand movement during music show performances.

Visiting Baegot Hanul Park today allows you to see the exact backdrop from that iconic scene. While the seawater pool is only open from June to August each year, the West Sea view and the new town skyline surrounding the pool are accessible year-round. If you time your visit with the sunset, you can also experience the breathtaking moment that visitors unanimously praise as 'the West Sea sunset is a true work of art.'
