For years, he has been known as singer Sunmi’s (선미) dedicated dance partner, earning him the nickname “Stage God.” Last year, Cha revealed he had been diagnosed with leukemia. After announcing his successful recovery late last year, he recently made a healthy return to the “Waterbomb Seoul 2026” stage, performing with Sunmi for the first time in a while. Their performance not only showcased their signature chemistry but also featured Cha lifting Sunmi high, creating a thrilling moment that moved fans, who exclaimed, “It’s so touching to see him back healthy.”

The most captivating moment of the show was the surprise appearance of Cha Hyun-seung, Sunmi’s dance partner of many years.
