Synopsis Won (Naret Promphaopun) is an anesthesiologist who lost his great love in a tragic accident and was falsely accused of murder. On the verge of taking his own life, he encounters a Grim Reaper named Sibsi (Krittin Kitjaruwannakul), who bears the exact face of his deceased lover. The Reaper repeatedly stops him from dying, revealing that their fates are intertwined.
