Both female leads find themselves in a difficult situation until they meet a man that will supposedly save them. They find themselves in situations where they end up faking their love (DAYS - so that he will die) (CLOY - So that she doesn't die or get caught as a South Korean). Through this, they both bicker quite a bit but eventually gain feelings for each other. Although they start to like each other, they both do not realise. The male leads have both made the promise to keep her safe but when she sacrifices herself, they become quite frustrated and realise they may have feelings.
