버림받은 황자의 유령 신부 / Beorim Badeun Hwangja-ui Yuryeong Sinbu / Cô Dâu Ma Của Vị Hoàng Tử Bị Bỏ Rơi / La novia fantasma del príncipe abandonado / The Ghost Bride of the Abandoned Prince / 捨てられ皇子は幽霊花嫁と暮らしています

A 300-year-old ghost becomes bound in an unwanted spirit marriage to Lucian, an eight-year-old boy who lives alone and survives on roasted potatoes. Though irritated by the arrangement at first, she feels sorry for him and secretly helps by cooking and doing his chores. Then she discovers that Lucian can see her. The lonely boy accepts her warmly as his “ghost bride” and gives her the name Ria. As the two grow close, Lucian promises that one day he will make her his real bride. They are later separated, and years pass before Lucian returns—not as the helpless child Ria once cared for, but as the emperor, determined to keep his promise.
