Sai Luead Hang Rak

Alin was abandoned as a child by her mother and raised by Mayu and Aunt Sroi. Her only link to her past is a locket engraved with the letter "P." Her life intertwines with Methas, the son of Nun Maratee, who has been tasked with retrieving a young boy named Frans. Frans's mother, Ingta, is dying of terminal cancer, but her sister, Tantung, harbors a deep hatred for Alin’s family, leading to a violent struggle for custody that results in Ingta's death. Alin successfully rescues Frans, and Methas convinces her to move to Bangkok to be the boy's nanny. Alin agrees, fueled by a hidden desire to settle unfinished business from her past.
In Bangkok, Alin reunites with her best friend, Chompoo, who is evading arrest for illegal phone trading. They are pursued by Wasit, a police inspector and Methas's close friend. Wasit falls for Alin at first sight, though Methas constantly interferes with his advances. Eventually, Wasit recruits Chompoo as an informant to catch a major criminal.
The day Alin has waited for finally arrives: she meets her biological mother, Pimchanok Wiriyakul, but Pimchanok has no memory of her. As Alin quietly searches for the truth, Pimchanok suffers a severe shock. This leads Alin to meet Phornphiphat (Pimchanok’s father) and Thanong (Pimchanok’s fiancé). Recognizing Alin’s locket, Phornphiphat realizes her true identity and ruthlessly orders Thanong to eliminate her. Thanong kidnaps and tortures Alin, but Methas manages to rescue her.
As Alin recovers physically and mentally, Methas sacrifices everything to care for her, leading to a falling out with his father, Aphinan. The two grow deeply bonded. Against the warnings of her friends, Alin approaches Pimchanok again, and the proximity begins to trigger Pimchanok's suppressed memories. Fearing her mother will be hypnotized to forget again, Alin "kidnaps" her with the help of Methas, Wasit, Chompoo, and Wasit’s brother, Saran. A confrontation ensues with Thanong’s men; Wasit shoots Thanong, but Wutthichai (Methas’s cousin) arrives later and finishes Thanong off. Wasit is left partially paralyzed in one leg from the skirmish.
With her memory restored, Pimchanok brings Alin back to the Wiriyakul estate, much to the anger of Phornphiphat and Phongphit. Alin proves her business acumen to Phornphiphat, causing his cold exterior to soften. This shift enrages Phongphit, leading to a conflict so intense it triggers Phornphiphat’s fatal heart attack. Before dying, he tearfully apologizes to Alin.
Just as Alin’s life stabilizes, Methas’s world collapses. His father becomes paralyzed, his company goes bankrupt, and Wasit turns against him. The mastermind behind these tragedies is Wutthichai and his sister, Pancharee. To destroy Methas and Alin, Wutthichai lies to Alin, claiming she and Methas are biological siblings. Devastated by the thought of an incestuous relationship and discovering she is pregnant, Alin distances herself from Methas.
Secretly, Alin agrees to marry Wutthichai to gather evidence of his crimes and reclaim Methas’s company, Thararak. When Nun Maratee arrives to care for Aphinan, Pancharee discovers that Methas and Alin are not siblings. Wutthichai immediately orders a hit on the Nun to keep her quiet. Eventually, Wutthichai’s greed leads to his downfall and death.
Wasit regains his ability to walk, fueled by his love for Chompoo, and mends his friendship with Methas. However, a final truth emerges: Methas is not Aphinan’s son, but the biological son of the villainous Thanong. Alin comforts him, encouraging him to be strong for their unborn child. Methas vows to protect Alin and their child—a bloodline that finally unites their love as one.
