Forbidden: Hate → Affection

After unexpectedly losing her husband, Amanda learns he was the eldest son of a billionaire family. Taken in by her mother-in-law, she forms a love-hate bond with her brother-in-law—they start as rivals, but gradually grow to respect and care for each other. Bound by their “sister- and brother-in-law” status, both suppress their forbidden feelings. It’s only after a major crisis forces them to face their truths that they stop holding back, embracing their love and ending up together.
