The CEO's Belated Bride

The female lead and the male lead get a marriage certificate after meeting only once. He has his assistant give her a bank card with its PIN, then drives off, disappearing from her life. Years later, he returns to the country to find the wife he hasn't seen for years. However, a series of misunderstandings creates a rift between them. Fortunately, they eventually resolve their issues, and the wealthy husband ends up cherishing her, protecting her at every turn.
