Serena, a medical prodigy from Columbia University, is sold by her greedy father for $3 million to Liam, heir of New York old‑money giant Nova Corp. She thinks she weds her Brooklyn savior from ten years ago, only to be humiliated on their wedding night — she is merely an heir‑bearing breeder, a substitute for his first‑love Chloe. Tormented by her arrogant mother‑in‑law, malicious rival and ruthless capital rules, she suffers miscarriage, betrayal and near‑death ordeals. Now the broken substitute bride comes back with deadly secrets to seize power atop Manhattan.
