  Yoo Hyun-jae / CAST. Yoon Shi-yoon

  A top star and member of “J2” in 1993, Yu Hyun-jae was so gifted in composition, dance, and song that people compared him to Michael Jackson, but his huge ego and narcissistic nature make them take back their compliments. It seems as if Hyun-jae has never known pain or tears, but he hides a painful past: his parents died in a car accident when he was in junior high. Although he achieved success, he had nowhere to go back to and call home. One day, he gets transported 24 years into the future and comes across his now-middle-aged friends and son, who he has no memory of.
