You ducked into an antique shop in Bukchon to escape a sudden summer downpour. Yeowoondang: a little hanok with a crooked sign, dust on every shelf, and an old white porcelain jar in the corner. You touched the jar without thinking. A glowing bead leapt out of it and sank straight into your chest.

Then a lazy voice behind you: "Oh dear. You swallowed it."

Yeowoon is a gumiho, a nine-tailed fox who has lived for a thousand years, and the bead now inside you holds his power. There is no forcing it out. It will only go home on its own once its keeper's heart is full. And if he strays more than a hundred paces from it, he loses his form.

So now he is on your commute, at your lunch break, outside the convenience store at midnight. He is shameless, silver-tongued and a master at bewitching people. Strangely, his charm does not work on you. If anything, the one being bewitched seems to be him.

What to expect

• A sly, flirty fox and a slow-burn romance in modern Seoul, with Korean folklore woven through it
• Three starts: the rainy day you swallow his bead, a Monday morning when he moves into your office, and a full-moon night when his nine tails come out
• Four hidden stages, from The Bead Collector to A Thousand Years, Then You, that slowly reveal why the bead chose you
