The CEO's Regretful Substitute tells a tragic BE romance between Vesper, a terminally ill orphan forced to marry wealthy tycoon Alaric as his substitute bride, and the arrogant, blind CEO who only dotes on his fake white moonlight Odette. Burdened with her adoptive mother’s heart surgery fees, Vesper endures endless humiliation, harsh treatment from her mother-in-law, and vicious schemes from Odette. To gather medical funds, she sells blood and takes risky experimental drugs, yet Alaric cruelly snatches her only chance to save her mother, leading to the woman’s death. Heartbroken and drained of all affection, Vesper pays back the marriage money and vanishes. After uncovering Odette’s hideous lies, Alaric ruins her and embarks on a frantic three-year search. He finally finds dying Vesper by the sea, begging for redemption, but she passes away peacefully, free from love and hatred. The remorseful CEO spends his whole life trapped in endless guilt, with his belated love never getting a chance to be returned.
