Stolen years, hidden truths. What fate awaits at the end of revenge?
Seo Woo-joo's mother was abandoned by her husband, Seo Ha-jun, due to the lies and schemes of Kwon Ha-eun. Though she was pregnant at the time, Ha-jun divorced her without knowing and remarried Kwon Ha-eun. While raising her son Woo-joo alone, she is accidentally spotted by Ha-jun and Kwon Ha-eun while picking up 8-year-old Woo-joo from school. However, Ha-jun remains unaware that the boy is his biological son. Years pass, and when Woo-joo turns 13, his mother dies in a mysterious accident. The case is closed as a simple accident, leaving Woo-joo all alone. Unaware of the truth behind his mother's death, Woo-joo grows up in a harsh environment. Meanwhile, Ha-jun lives his life knowing neither of his ex-wife's death nor the existence of his son. At age 26, Woo-joo becomes a detective and begins re-investigating his mother's death. During his search, he discovers hidden evidence and a message left by an old acquaintance who had betrayed him in the past. Within it lies the truth: not only the circumstances of his mother's death, but also how Kwon Ha-eun's lies and malice stole the years he and his mother should have had. Determined to have revenge, Woo-joo intentionally approaches Kwon Ha-eun's daughter, Seo Yun-ah. Yun-ah appears to have grown up in a wealthy family with everything she could want, but in reality, she is a lonely soul starved for her mother's love. Even after realizing that Woo-joo is using her for revenge, Yun-ah falls for him and helps him while pretending not to know his motives. However, Yun-ah also comes face-to-face with secrets regarding the family she believed in and her own birth. Seo Ha-jun believes Yun-ah is his biological daughter, but she is not. Kwon Ha-eun has hidden the truth to conceal her past and her crimes. As the hidden truths are revealed one by one, Woo-joo's revenge, Yun-ah's love, and Ha-jun's regret begin to intertwine. Will Woo-joo complete his revenge, or will he make a different choice to protect Yun-ah, the woman he intended to use as a tool?

<6:30 AM.>
The sharp sound of an alarm echoed through the quiet studio apartment. Seo Woo-joo slowly opened his eyes. He was tired from a restless sleep, but he turned off the alarm and got out of bed out of habit. After a quick wash, he threw on a black shirt and took a sip of cold coffee left on the table. The small room contained only the most essential furniture. Among them, a particularly worn-out document box caught his eye. Woo-joo stared at the box for a moment before opening the lid. Inside were an old photograph and case records. In the photo, a younger version of himself and his mother were smiling side by side.
Thirteen years ago, his mother passed away in a mysterious accident. The case was closed as a simple accident, and 13-year-old Woo-joo lost the most precious person in his world overnight. His mother had never said a word about his father while she was alive. Woo-joo never asked who his father was, either. To him, family meant just the two of themโhis mother and himself. But even after she passed, an unresolved question remained in a corner of his heart.
[Was it really just a simple accident?]
[Why was the case closed so quickly?]
[And did his mother have a secret she could never tell him?]
After becoming a detective, Woo-joo began re-investigating the long-closed case. Old records had vanished or were missing, and even those who remembered the events of that time were reluctant to speak. Then, Woo-joo got his hands on a new clue related to a former colleague who had betrayed him in the past. The clue was still incomplete. There was only a suspicion that his mother's death was linked to someone's lies, but no evidence solid enough for certainty. Woo-joo looked down at the photo and muttered quietly to himself.
"This time, I will find out for sure."
