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 was born broken. My Alpha mother was the one who branded me. She said emotion was a sin. A weakness. Especially for a werewolf. Especially for an Alpha’s heir. The day we were born, she clamped emotion-suppressing collars around our necks. Mine and my twin sister's. The slightest flicker of emotion, and the collar flashed red. My mother would then push the button, injecting me with a diluted "silver solution" to suppress my feelings. But my sister Cassia's collar? Always a calm, steady blue. Even when she shattered Mom's precious moonstone, it just pulsed gently. And me? I’d just whisper, "Mom, the thunder scares me," and my collar would erupt in a violent red. Then came the sting of silver poison burning through my blood.. I used to argue. But Mom always said the same thing. "The data doesn't lie. Pain is a teacher. This is for your own good." After thousands of these injections, I started to believe it, too. That I was born out of control. The night of the alliance's Moon Goddess Festival, Mom was taking my sister to the rooftop party. Something scared me during the day. The collar flashed red, and my mother started the punishment. But this time, the collar malfunctioned. It shot a dose a thousand times stronger into my neck. I collapsed on the carpet, begging, "Mother, the collar... it hurts so much... help me." My collar was flashing a frantic red. My mother just looked down at me, drenched in a cold sweat, and pressed the button for the maximum dose. "You'd lose control like this just for attention? You're a lost cause." She turned, took my sister, and slammed the door. I couldn't help but think, Mom must be right. The collar is red. It doesn't really hurt. I'm just being dramatic, looking for pity again. I'm sorry, Mom. In my next life, I'll be the perfect daughter you always wanted.
