While the chemistry of Gong Yoo and Kim Go Eun was noted and expected previously, Lee Dong Wook, who portrays the role of the Grim Reaper and Yoo In Na, who plays the role of Sunny is reportedly expected to add more romance and thrill to the newest tvN drama.

According to one fan theory, Grim Reaper (Lee Dong Wook) might be the King and Sunny (Yoo In Na) as the Queen who was killed in the first episode. Moreover, the theory revealed that since the dead king's body was not shown, some fans assume that it is because it will soon be revealing Lee Dong Wook as the face of the grown up king who regretted killing Gong Yoo's character, Kim Shin.
