Shen Qingci is a gifted counselor who can see a mark on those nearing death. The Underworld “specially hires” her to soothe the lingering attachments of the dead and help them reincarnate in peace. Then she is forced to work with a new partner sent by the Underworld: Lu Li, her former boyfriend, a police detective who died in the line of duty five years ago and now calmly wields a soul-hooking chain. From then on, her counseling room sits at the boundary between life and death. She uses cognitive therapy to untangle the grudges of vengeful ghosts and Systemic Constellations to lay the grievances of tormented household spirits to rest. Yet a string of bizarre deaths all seem to point back to her unusual ability to see into both worlds. With her ex now her boss as a “grim reaper,” and a second chance at love colliding with the death register’s KPIs, she must not only heal the dead, but also face the whirlpool of conspiracy and fall in love with him through life and death once more.
