Arriving in Seoul, the first thing that Jung Eunji realises is that not everything is as it seems. In a place buzzing with life and activity, she finds herself drawn to the darker corners. When she is chased by a group of people out of the blue, she finds temporary safety with ones who call themselves Cursers, people who have the special ability to cast magic, or, as the Cursers themselves call it, Curses. But, all magic comes with a price and for one particular boy, every time he uses his Curse, his capability to love shortens. Strangely, Eunji finds herself wanting the remainder of his love.

"All magic is cursed. Nothing comes without a price."
