The heart of 'Sweet Revenge' revolves around the life of Pelin, portrayed by the talented Leyla Lydia Tugutlu. Pelin is a young and beautiful woman who, despite her efforts, seems unable to find true happiness in love. Determined to change her fate, she embarks on a journey that takes an unexpected turn. She believes she has found her prince charming in Tolga, played by Can Nergis, and the two prepare to exchange their vows on their wedding day.
However, fate has different plans for Pelin. In a shocking twist, Tolga leaves her at the altar, plunging her into a deep depression. Searching for answers, Pelin uncovers a painful truth – her present misfortunes are the consequence of a past mistake. To pave the way for a brighter future, Pelin must seek forgiveness from someone she wronged in the past.
As Pelin delves into her past, she discovers that her quest for redemption hinges on obtaining forgiveness from Tankut, portrayed by the charismatic Furkan Andic. Tankut was once deeply in love with Pelin during their college days, only to be publicly humiliated by her in front of their peers. Despite the passage of time, Tankut's heart still harbors the scars of that painful experience.
