Two days after the next heaven-bound train, the time granted in this world is two months! Young-soo (Hae-joon), excited to have returned as a handsome man with the perfect, muscular body he always dreamed of, and Gi-tak (Hong-nan), in deep despair, having returned contrastingly as a beautiful woman with a high voice and slender body type. The two who must live as Hae-joon and Hong-nan for two months each make their way to their workplace and learn surprising truths hidden after their deaths. Meanwhile, Maya, having become anxious due to Young-soo's (Hae-joon's) return error, to hide the real Lee Hae-joon's identity uses her last resort. (Source: KOCOWA)
