In the shadowy heart of Seoul near Cheonggyecheon Stream lies a sinister mansion whose porch only fools would dare tread. Welcome… to the house of the Ki sisters: Jang-nyeo, Sal-gyo, Jae-rim, and Jenny. Homeschooled and raised in isolation, the four sisters and their inadvertently menacing demeanor may strike terror into the faint-hearted, but don't judge a book by its cover: the youngest, Jenny Ki, is a scary-- I mean, starry-eyed hopeless romantic who's out to find love! The problem is… everything she knows about love is from romance novels. Will Jenny put the Ki in “kiss” or “kill”?
