Marry My Husband: Japan

A reverse romantic comedy about a "shotgun romance" that begins with a one-night stand between a man and a woman who both vowed never to get married in this lifetime.

Kang Du Jun, a seemingly perfect second-generation chaebol from head to toe. Having decided that marriage was not in the cards for this life, he lives for his remaining family and company in place of his deceased older brother. However, his life takes an unexpected turn when he becomes entangled with Jang Hui Won after a wild one-night fling.

Jang Hui Won, a career woman who scores 100 in work but 0 in romance. Scarred by her parents’ divorce and a harsh upbringing under a cold, critical mother, she has shut herself off from the idea of marriage and embraced singlehood by choice. But her carefully structured life faces an unforeseen twist following that one impulsive night.
