The Ferrymen Of the Frozen River

Kai has a new assignment - escorting one Choi Soobin to the Underworld. He passes by Beomgyu's desk and finds him staring at a photograph. It's someone Beomgyu used to know and by extension, someone whom he definitely shouldn't be escorting to the Underworld. There's rules for that. Unfortunately for Beomgyu, when he reaches the scene, he succeeds in shocking his dead acquaintance back to life but ends up escorting his dying 'murderer' to the Underworld instead. Choi Yeonjun is none too happy about dying. Kang Taehyun, having seen Beomgyu is not happy about having to live. And Choi Soobin is outright hostile to his rather gentle Grim Reaper, plotting the dead man's death.
