Soyou channeled her spooky side while appearing as a special guest at MC Mong's recent concert.

The singer is among the number of special guests invited to perform at MC Mong's 'Monsters, Inc. - 2nd General Meeting of Shareholders: Halloween Workshop' concert, a Halloween-themed event held on October 22 and 23 KST at KBS Arena. Other guests invited include ballad singer Huh Gak, rapper BE'O, and Lee Mujin, all of whom are Soyou's agency Big Planet Made.

During the concert, she dressed up as a corpse bride, performing on a stage decorated to match the Halloween mood.

She also took to her personal Instagram account on the same night to share some behind-the-scenes concert photos of her in her costume, captioning the post with some playful ghost emojis.

Comments left from Soyou's Instagram followers include, "Where is there such a pretty ghost?," "No way, how are you still pretty even with this makeup?," "This kind of ghost is always welcomed," and "'Corpse Bride' live-action version... Ah, you're freaking pretty. I love you!"
