The female lead, the backbone of her husband's company, happily returns home after closing a million-dollar deal with a client — only to discover her husband having an affair with his mistress, right there in their own home. Devastated and furious, she goes to a bar to drown her sorrows and decides to divorce him. There, she unexpectedly runs into the client manager she'd just negotiated with that day, and they end up spending the night together. The next morning, she panics, rejects his confession, and flees. What she doesn't know is that the client manager is actually the hidden heir to the entire conglomerate — and he fell for her at first sight the moment he saw her during the negotiation.
