Going to the Troll's Kingdom

On the night of her grandfather’s funeral, Hwang Keum Lin catches sight of a thief trying to take something from his house. She pursues him before he can steal anything valuable, but he vanishes as if by magic. Her cousin refuses to believe her, and although nothing appears to be missing, Keum Lin is left wondering what the thief wanted and how he got past the house’s powerful security system. The strange break-in is only the beginning. From that night on, Keum Lin’s life is turned upside down, and the things she thought she knew may not be what they seem.
