Young K also reveals the behind-the-scenes story of his participation in the OST "The Season Returned" for the drama *Brave New World* for his best friend, Heo Nam-jun. He then delivers a first-ever live performance on the spot, completely captivating the "Choi Woo-su-san" members. I heard it airs tonight (the 28th) at 6:05 PM. I definitely have to watch it! I'm so curious! Hahaha.
