On her wedding night, FL hangs up on her demanding mother-in-law, only to learn the woman is paralyzed from "shock"—guilt-ridden, she abandons her dreams to care for her. When the MIL tears up their marriage certificate, FL tries to renew it and discovers she’s already divorced. Confronting her husband reveals the truth: the paralysis was faked to force him into marrying her best friend’s scheming daughter. Betrayed, FL turns guilt into revenge.
