Kang Do-hyun chooses an ordinary life as a taxi driver to avoid inheriting his father’s family business. One day, he happens to rescue Cha Eun-seol, who is fleeing a chase and has accidentally taken the wrong medication. After a one-night encounter, they part ways and return to their separate lives. Four years later, a stylish CEO shows up with a child and proposes marriage to Do-hyun. After registering their marriage, Eun-seol faces pressure from her parents to abandon the child, but Do-hyun appears and protects both mother and daughter. As her company falls into crisis, Eun-seol attends a family banquet of Taegang Group—the most powerful conglomerate in Country A—to secure a 10-billion-won investment, unaware that the chairman is actually her husband’s father. At the banquet, despite pressure from her former fiancé Gu Jung-tae, Do-hyun’s father protects his granddaughter Kang Rumi and makes his presence known, yet he can only approach her as a “grandfather” without revealing his true identity. As time passes, Do-hyun and Eun-seol grow closer. However, after failing to secure investment, Eun-seol risks both her company and her board position by making a dangerous bet with her father, Cha Myung-hwan. At this critical moment, Do-hyun seeks out his father, accepts the responsibility of becoming the heir, and begins to take action himself. In the end, at a press conference, the capital and influence Do-hyun has prepared turn the situation around. Eun-seol not only saves her company but also secures full ownership, achieving both love and success.

I lost all strength and collapsed to the ground. “Lemon water’s full of vitamin C. It helps with hangovers and keeps you healthy.” Charlotte Whitmore laughed so hard she nearly doubled over. With her arms crossed, she looked at my fiance, Ethan Cross, the boss of the Rolling Stones. “Ethan, your fiancee’s acting is incredible! “I’ve been a doctor for years, and I’ve never seen anyone react like this to a little champagne and lemon water.” I bit my lip until I tasted blood. The pain made my eyes sting, and I clutched Ethan’s leg. “Honey, please, call an ambulance! I can’t take it anymore…” For a moment, his expression wavered, but the guests quickly cut in. “Come on, stop pretending!

He yanked my hand off and stepped away. “Charlotte’s a doctor. You’ll be fine with her here.” I stopped begging and texted my father asking for help
