Sunja: If we marry quickly she'll be put at ease.
Koh Hansu: Why are you suddenly speaking of marriage? I thought you knew what this was.
Sunja: Knew? What does that mean?
Koh Hansu: I can't marry you. I have a family. In Osaka, I have a wife and three daughters. It's not exactly a marriage of love, but a necessary arrangement.
Sunja: A necessary arrangement?
Koh Hansu: Necessary for business reasons. There's no affection.
