If you are a lover of doormats being reborn and getting their revenge, Marry My Husband is the perfect Kdrama for you. For in this show, karma is indeed the main character's best friend.
It's confusing, I know. And it certainly creates the opportunity for comedy gold but it's also incredibly infuriating. You see, the love square's main purpose is to show the audience just how compatible these two characters are. They are, quite literally, made for each other. And I say literally because Ladybug holds the miraculous of Creation while Cat Noir holds the miraculous of Destruction. The are the yin and yang of this universe.
