Elara Voss, a top‑tier architect, discovers her husband Daniel’s double betrayal with her best friend on their third wedding anniversary. Thanks to a harsh prenuptial agreement, her cheating ex‑husband can still claim most of her assets, and a drawn‑out divorce battle would ruin her professional reputation.
At her lowest point, business tycoon Alexander Blackwood offers her a contract marriage. To secure his group’s controlling stake and fulfill his terminally‑ill mother’s last wish, they will pretend to be a loving couple for one year. Once the contract ends, he will settle her divorce lawsuit and pay her five‑million‑dollar compensation.
Both haunted by past wounds, they start out putting on an act for business rivals and relatives, yet gradually grow fond of each other as they spend time together. Victor, his power‑hungry cousin, schemes repeatedly to expose their fake marriage and seize corporate control. Refusing to back down, Elara teams up to unmask his plots.
Devastated by his mother’s death, Alexander drops his facade, and the two confront their genuine feelings for one another. As the contract nears its end, he tears up all transaction terms and proposes a real marriage to her. Free from her ex‑husband’s harassment, Elara realizes her architectural dreams. They finally hold a wedding atop a building she designed herself — a ceremony built on love, not interests.
