Thus begins a marriage born of sheer mishap: from workplace clashes to fighting shoulder to shoulder, from misunderstanding and testing to wholehearted devotion. Through the crisis of a three-hundred-million-dollar project and the skepticism of high society, the two prove their worth with ability and shield each other with sincerity—turning an accidental marriage into a love that both hearts run toward.
