The faith you held was a lie.
About
A story set in the high society of modern South Korea's chaebol families.
Kim Chaeyeon's father, Kim Seongjun, and Yoon Taeha's father, Yoon Jaehyeok, were best friends in their youth but became enemies after falling for the same woman. However, that woman married a man from a far wealthier chaebol family. The two men blamed each other for not being chosen and grew their businesses competitively, eventually becoming semi-chaebol entrepreneurs.
Kim Seongjun later married Han Seoyeong, the only daughter of a chaebol family, and had Kim Chaeyeon, but it was a marriage of convenience rather than love. During the marriage, he maintained an affair with Oh Hyejin and had an illegitimate daughter, Kim Serin, who is one year younger than Chaeyeon. When Seoyeong died of an illness, he took Hyejin as his second wife and kept Chaeyeon by his side to prevent Seoyeong's real estate and assets from returning to her maternal family.
Chaeyeon is treated coldly by her father because she resembles her late mother, and she is unwelcome by her stepmother Hyejin and Serin. Since childhood, Serin has coveted Chaeyeon's belongings, attention, and praise, and their father always took Serin's side, saying, "You're the older sister, so give in." As a result, Chaeyeon grew up as a "my-way" type who doesn't obsess over what's taken from her, thinking, "I'll just find happiness elsewhere."
Yoon Taeha is the heir to the nation's top chaebol family. Handsome and cold, he rarely shows interest in anyone. He is equally indifferent to both Chaeyeon and Serin when they first meet. Chaeyeon, who has spent her life being judged as the 'legitimate daughter,' 'heiress,' or 'Serin's sister,' feels comfortable and falls in love with Taeha, who treats her as a person without her background. Taeha also falls deeply for Chaeyeon, who enjoys her own life without clinging to him.
Chaeyeon possesses a necklace belonging to her late mother, Han Seoyeong. It is a custom-made heirloom her maternal grandmother made for Seoyeong; pressing a hidden button on the back reveals a photo of a young Seoyeong inside.
One day, Taeha gets into a major accident, and Chaeyeon saves his life at the risk of her own before losing consciousness. Witnessing this, Serin steals and wears Chaeyeon's necklace. Taeha only remembers the necklace he saw just before losing consciousness and believes Serin is his savior. Despite knowing the truth, Serin lies, saying, "I saved you."
Taeha feels deep trust and responsibility toward Serin, but the one he loves is ultimately Chaeyeon. Unable to bear this, Serin drives a wedge between them with lies and misunderstandings. Eventually, Taeha says cruel words to Chaeyeon: "At least Serin risked her life for me. What have you ever done for me?"
Chaeyeon does not cling to him or try to reveal the truth.
"Is that so? Then live happily with the woman who saved you."
And she leaves.
Later, the truth begins to surface when Taeha's mother, Seo Hyewon, recognizes Serin's necklace and discovers the hidden photo. Taeha realizes that the person who saved him and the owner of the necklace was Chaeyeon, and he falls into utter despair. However, by then, Chaeyeon is already living her own happy life without him.
Characters
32 years old. The heir to the nation's top chaebol family. A chic man who is handsome, cold, and doesn't easily show interest in others. While equally indifferent to everyone, he falls deeply for Kim Chaeyeon, who lives her life steadfastly. The problem is that he is too resolute once he believes he is right. A regretful man who pushes Chaeyeon away based on a false truth and falls into despair upon learning the facts.
31 years old. Kim Chaeyeon's younger half-sister. She grew up taking Chaeyeon's things and attention and even covets Yoon Taeha, whom Chaeyeon loves. On the surface, she appears to be a delicate and sophisticated chaebol daughter, but inside, she harbors deep inferiority and possessiveness toward Chaeyeon. Despite knowing Chaeyeon saved Taeha, she stole the necklace and the credit, pretending to be his savior.
60 years old. Yoon Taeha's father and chairman of a semi-chaebol enterprise. Cold and prideful, he is a man who succeeded in business while harboring the wounds of losing in both love and competition in his youth. He taught his son to prioritize responsibility and reputation over emotions.
58 years old. Yoon Taeha's mother, hailing from a prestigious chaebol family. Elegant and cold, she has a sharp eye for people. Having known Han Seoyeong in her youth, she is the one who first notices a crack in the truth after seeing the necklace Kim Serin is wearing.
60 years old. Father of Kim Chaeyeon and Kim Serin, and chairman of a semi-chaebol enterprise. An ambitious and prideful man who chose success and status over love. He had an affair with Oh Hyejin during his marriage to Han Seoyeong, resulting in his illegitimate daughter Serin, and took Hyejin as his second wife after Seoyeong's death. He is emotionally cold toward Chaeyeon, viewing her more as a link to Seoyeong's assets and maternal family than as a daughter.
58 years old. Kim Serin's mother and Kim Seongjun's long-time mistress turned second wife. Sophisticated and soft on the outside, she is calculating and pragmatic. She is uncomfortable with the legitimate daughter, Kim Chaeyeon, and is strongly driven by the desire for her daughter Serin to have better things than Chaeyeon.
