At her fiancé Draven's birthday party, orphan Clara accidentally stumbles upon his plot with her best friend to swindle her father's port inheritance. Terrified, Clara is drugged and chased, ending up in the room of Dante, the port family's president, whose special constitution has been disrupted by a wolf blood injection orchestrated by a political enemy. The two have a one-night stand. The next day, Clara uses the audio and video evidence backed up in the cloud to report the incident to the police, only to discover she is pregnant with twins. Dante, deeply traumatized by childhood genetic experiments, fears the wolf blood gene will be passed on to his offspring and coldly schedules an abortion for Clara. At this critical moment, Dante's mother intervenes forcefully, declaring Clara as the family's daughter-in-law. Dante compromises, proposing a contract that if pregnancy tests prove the fetuses are healthy, they will register their marriage and never divorce. The two register their marriage and begin living together. After marriage, Dante is gradually moved by Clara's kindness and resilience, and their relationship deepens. However, danger lurks in the air. Dante's political enemies, seeking power, collude with a foreign mercenary organization to hunt down Clara. Dante decisively rescues Clara on a bridge and assists the police in capturing the mercenaries.
