CEO, She Left With the Divorce Certificate

The fire and the drugging that Luchi held against his wife were both arranged by Song Chu-eum, the woman he had loved before the marriage. Kang-hee had married him three years earlier on her grandfather's orders, after an accident, and she gave the marriage everything for those three years without reaching him. When Song Chu-eum comes back, Kang-hee files for divorce. The truth about the fire and the drugging comes out while the divorce goes through, and Luchi sees what he had been blaming her for. She takes the divorce certificate and goes abroad to study on the strength of her design work. Luchi regrets it after the fact and starts on the long business of trying to get her back.
