Happy Birthday, Gianna Jun! From your iconic sass in "My Sassy Girl" to the fierce mermaid charm of "Legend of the Blue Sea," you've effortlessly captured hearts and laughter worldwide. Honestly, we're still trying to perfect that legendary hair flip—teach us your ways!

Your recent brilliance in "Kingdom: Ashin of the North" reminded us why zombies should never mess with you. May this birthday bring as much joy and excitement as you've given fans through every unforgettable role. Keep dazzling screens (and slaying monsters) for many more years—we'll be cheering from our couches with popcorn ready!
