Guseurui Juin

Lee Jinhwa lived an ordinary life until she swallowed a fox bead gifted by a mysterious peddler, mistaking it for a wish-fulfilling marble. Little did Jinhwa know that her actions would lead her to be haunted by Koo Miho, an infamous nine-tailed fox who wishes to retrieve the bead. To add fuel to the fire, Jinhwa soon discovers that she's also become a target for various spirits and demons, and the only way to extract the cause of the issue is for Miho to kill her... or kiss her!
