Okay, this drama sounds like a mash up off Goblin’s cohabitation element and Tale of Gumiho‘s fox bead aspect, and Tale of Gumiho ended up being a stupid and lame mashup of Goblin and Hotel Del Luna. I would castigate this drama for retreading except it’s based on a manhwa as tvN will air the K-drama adaptation of Falling Cohabitation with Jang Ki Yong and Hyeri in early 2021. Jang Ki Yong plays a male gumiho who has lived for 999 years and is prepping to become a human. He loses his fox bead and cannot become human without it, and Hyeri is a college student who swallows the fox bead and will die within 1 year because her body cannot withstand it, unless it is removed. They two start to live together and romance ensues. I…..have no comment right now, on either the story or casting, because I’ve been burned so many times by this genre and also both leads. Let’s hope for the best, folks!
