Actor Park Seo Joon posted a photo on his Instagram with Hyungsik and V, demonstrating a brotherly bond among the 'Hwarang' cast. The actors had attended BTS' concert in Seoul. The caption cleverly reads, "I recognized you at first sight," a line from BTS' "DNA".
Another photo featured V with actress Ha Ji Won as the two looked like siblings in front of the camera. The caption read, "Every moment was a perfect stage just like a movie. BTS is the best in the world!"
