My stepsister falsely accuses me of causing her allergies to act up. My three brothers stuff me into the cramped cellar and chain the door shut. I pound on the door and beg them to let me out. My eldest brother, an outstanding businessman, snaps, "It's bad enough that you keep bullying Lori. How could you make her eat seafood when you know she's allergic to it? Isn't that just murder? Stay in there and reflect on your mistakes!" My second brother, an award-winning singer, and my third brother, a genius painter, scoff contemptuously. "It's unbelievable that someone as evil as you is making excuses to garner pity. You can stay in there and repent for your sins!" After that, they take our shuddering stepsister to the hospital. The oxygen in the cellar soon runs out, and it gets difficult to breathe. Ultimately, I die in there. My brothers only remember me three days later when they bring our stepsister back from the hospital. Unbeknownst to them, I've already died of asphyxiation.

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.
