Missing You

After returning from the United States, Jung-woo meets a mysterious girl named Soo-yeon, who asks if he remembers her. Realizing she is the girl who once gave him a yellow umbrella in the rain, he searches for her at his new school to return it. Instead, he learns that Soo-yeon is infamous as the "murderer's daughter."

Branded the "murderer's daughter," Soo-yeon is relentlessly bullied and lives with her head bowed in shame. Jung-woo promises to be her friend and keeps that promise even when she asks to remain "secret friends."

After sharing their deepest secrets and scars, Jung-woo and Soo-yeon become true friends, their bond growing stronger despite relentless bullying and jealousy. But one night, while on his way to meet Soo-yeon, Jung-woo is ambushed by mysterious attackers.

Haunted by the guilt of leaving Soo-yeon behind, Jung-woo tells Detective Kim everything that happened that night. After learning the truth, Detective Kim promises to find her.

Despite their desperate search, Jung-woo and his family find no trace of Soo-yeon, clinging to the hope that she is still alive. Fourteen years later, Jung-woo has become a detective. Still unable to let go of the past, he visits Sang-deuk, the kidnapper responsible for Soo-yeon's disappearance, just before his release from prison.

Soo-yeon returns under the new identity of Zoey, a successful fashion designer, with her longtime partner Harry by her side. On a rainy night, Jung-woo hears a hauntingly familiar voice outside Harry's home.

When the mysterious woman calls Jung-woo by name, his confusion deepens. Noticing Zoey's shaken reaction, Hyung-joon becomes increasingly uneasy. Unable to ignore what he witnessed, Jung-woo tells Soo-yeon's mother that he has seen someone who looks just like her long-lost daughter.

Zoey struggles to remain composed after her repeated encounters with Jung-woo, but realizes that her resolve is beginning to waver. Meanwhile, convinced that Zoey is the Soo-yeon he has been searching for all these years, Jung-woo sets out to confront her.

Jung-woo is overwhelmed by guilt for failing to protect Soo-yeon years ago. Meanwhile, Zoey becomes the prime suspect in Kang Sang-deuk's murder.

After a long search, Myung-hee tracks down Harry's home and is finally reunited with her daughter, Soo-yeon. Overcome with emotion, the two confront the painful memories that kept them apart for years.

Jung-woo suddenly disappears while tracking down the culprit's whereabouts. After receiving a phone call from Jung-woo, Soo-yeon insists on searching for him, much to Harry's dismay.

Fearing that his inability to let go of Soo-yeon will only burden Zoey, Jung-woo resolves to distance himself from her. Meanwhile, he intensifies his interrogation of the cleaning lady arrested for Kang Sang-deuk's murder.

Realizing that Jung-woo has spent the past 14 years burdened by guilt and longing for her, Zoey joins him at the playground where they shared childhood memories. Meanwhile, Harry is overcome with anger after hearing from Jung-woo that he has found Soo-yeon.

Jung-woo is taken off Kang Sang-chul's murder case but continues investigating on his own, realizing the killer deliberately left the body for him to find. Meanwhile, determined to uncover the truth behind Detective Kim's death, Zoey begins piecing together long-buried memories from 14 years ago.

Angered by Harry's hysterical behavior, Jung-woo warns him that he can get even closer to Zoey whenever he wants. Meanwhile, Jung-woo returns to his father Han Tae-joon's house for the first time in 14 years, where he comes face-to-face with an unexpected person.

Harry becomes furious when Zoey tries to recover her past memories from him, while Zoey feels unsettled by this. Meanwhile, after quitting the police force, Jung-woo packs his belongings and moves into his father Han Tae-joon's house.

After learning that Jung-woo is the little boy Harry rescued from a fire 14 years ago, Jung-woo desperately goes looking for Harry. Exhausted by how completely Harry has changed, Joey tells Jung-woo that she wants to go back to her mother's home.

Soo-yeon is framed for murder after Harry fabricates evidence against her. Together with Jung-woo, she embarks on a desperate escape to stay alive. Meanwhile, Harry is discovered in a secret room after destroying the evidence and begs the detectives investigating the case to find Soo-yeon.

Leaving their fleeting moments of happiness behind, Jung-woo and Soo-yeon return to Seoul. Soo-yeon faces police interrogation once again.

Having secured evidence that Harry is the culprit, Jung-woo chases after Harry as he flees to avoid arrest. Meanwhile, Jung-woo hears an unexpected story from his stepmother, Hwang Mi-ran.
