Amidst the number of different cameos in KBS’s “Descendants of the Sun,” the drama went out with a bang by bringing on one of K-pop’s hottest girl group acts, Red Velvet!

Spoiler

In the final episode of “Descendants of the Sun,” the girls of Red Velvet put on a performance to boost the morale of the soldiers, singing their 2015 hit “Dumb Dumb.” Yoo Si Jin (Song Joong Ki) and Seo Dae Young (Jin Goo) prove to be huge fans, cheering them on with fervor. Yoo Si Jin even carries a sign that says, “Red Velvet over my girlfriend.”

When Kang Mo Yeon (Song Hye Kyo) sees her boyfriend holding the fan sign, she goes straight into denial, saying, “That’s not Yoo Si Jin.”
