Mousetrap Episode 10 — Hindi Dubbed

Mousetrap Episode 10 brings the identity mystery to its final and most disturbing stage. Moon-jae is still trying to understand the memories returning to him when The Rat contacts him and confirms that their final meeting will take place on Jeju. The destination is not random. The ship, the sea and the location are connected to the beginning of their tangled history, and The Rat intends to disappear after their confrontation, leaving Moon-jae to face the consequences of everything that has happened. Before Moon-jae can reach Jeju, the police continue searching for Han Hui-su. The elderly man has disappeared again, but a railway worker remembers seeing him asking how to reach Children's Grand Park. Detective Park Sun-yong realizes that Hui-su may be trying to return to a location connected to his memories rather than simply running away. The police also know that Moon-jae and The Rat are both moving toward the same final confrontation. Meanwhile, Noja survives his brutal fight with Seung-gyu but is badly injured. His arm has suffered permanent damage, leaving him unable to use it normally. Seung-gyu has also been badly beaten, but both men survive. Noja realizes that his life as a violent enforcer has finally reached its limit. He decides that the injury is a sign that he should retire from the criminal world and return to a quieter life. Moon-jae boards the ship bound for Jeju, following The Rat's instructions. The Rat has arranged for both men to be aboard, knowing that the isolated environment will give them the privacy needed for their final confrontation. As the ship moves across the sea, Moon-jae begins experiencing fragments of his past that he had forgotten because of his medication and psychological trauma. The confrontation finally happens inside the ship. Moon-jae meets The Rat face-to-face and demands to know why he has spent so much time destroying his life. The Rat responds that Moon-jae has misunderstood everything. His goal was never simply to steal another man's identity. He wanted to take back the life, talent and future that Moon-jae had already stolen from him years earlier. The Rat reveals the truth about Seo Yu-min and So Min-yeong. Years earlier, Moon-jae had been jealous of Yu-min and Min-yeong's relationship. He anonymously posted cruel stories about Min-yeong online, mixing real details with lies and exposing private aspects of her relationship with Yu-min. The rumors became so damaging that Min-yeong abandoned her graduate-school plans, cut ties with her family and fell into severe depression. Yu-min explains that Min-yeong eventually attempted suicide by taking pills. He stayed beside her, but he had no money to pay for the help she needed. Desperate to save her, he took his writing to a publishing house. There he discovered the horrifying truth: his own novel had already been published under the name Je Moon-jae and had even won the Best New Writer award. Yu-min realized that Moon-jae had stolen his notebooks, his stories and the experiences he had written about. Moon-jae had transformed Yu-min's life into his own literary career. Even worse, Moon-jae had taken Min-yeong away from him. Yu-min spent countless nights reading the novels that had been built from his own work and decided that revenge was the only thing left to him. The Rat admits that this is why he became obsessed with becoming Moon-jae. He wanted to take back everything that Moon-jae had taken from him. His plan was to strip Moon-jae of his name, career, property and reputation and force him to experience what it felt like to have an entire life stolen. Moon-jae initially refuses to believe the story. He accuses Yu-min of being a liar who had fabricated his entire history. He insists that Min-yeong was his girlfriend and that the notebooks belonged to him. Yu-min responds that Moon-jae has confused the stories in his novels with his actual memories. The memories Moon-jae believes are his may have been created from Yu-min's life and writing. The confrontation triggers a flood of memories inside Moon-jae. He suddenly remembers his college years and begins to understand why so many details of his past never made sense. He realizes that his memories of Min-yeong, Yu-min and the literature club were deeply distorted. The more he remembers, the more frightening the truth becomes. Moon-jae finally understands the source of his long-term writer's block. After becoming famous, he had eventually run out of material because the stories he had used to build his career were not truly his. The talent he believed defined him had been built on someone else's notebooks, experiences and imagination. His inability to write was therefore not simply a creative problem; it was the psychological consequence of living inside a stolen identity. At the same time, another shocking family revelation emerges. Yu-min tells Moon-jae that the detective, Park Sun-yong, is actually his older brother. Before Moon-jae was born, the original Je Moon-jae was the real child connected to the family. According to Yu-min, Moon-jae himself was placed into that identity from the beginning, meaning that the identity crisis is much older than the theft that began the series. Yu-min explains that Sun-yong had been sent back to an orphanage and that Moon-jae was placed in his position. This revelation leaves Moon-jae questioning everything about his childhood, his parents and the name he has carried throughout his life. He realizes that he may have been living under an identity that was never originally his. Yu-min's revenge plan reaches its final stage when he prepares to disappear after the confrontation. He believes that if Moon-jae had gone directly to the beach as instructed, Yu-min could have vanished and left the world believing that Moon-jae was the monster behind the crimes. Instead, Moon-jae has followed him aboard the ship, forcing the two men into a direct physical confrontation. As the two fight, Yu-min asks Moon-jae whether he still wants to be him. Moon-jae finally gives an unexpected answer. He says that he does not think he ever truly wanted to be Yu-min. What he wanted was to be himself—a better version of Moon-jae. His mother's old advice about becoming the best version of himself finally takes on its real meaning. The fight becomes violent and Moon-jae eventually throws Yu-min from the ship. Yu-min falls into the sea and disappears. His body is not recovered, leaving the circumstances of his death impossible to establish conclusively. Moon-jae survives and is able to present the event as an attack by the impostor who attempted to kill him. When the ship reaches its destination, Moon-jae tells the authorities that the other man had secretly boarded the vessel and tried to kill him. He claims that the impostor attempted to throw him out of a window but fell into the ocean himself. The available evidence appears to support his version of events, especially because the police cannot recover Yu-min's body. Han Hui-su is eventually located alive, and the police are finally able to pursue the DNA test that could settle the identity question. Moon-jae confidently presents himself as Je Moon-jae and says that the test will prove who he is. He believes that with Yu-min gone, his identity is finally safe. But Detective Sun-yong is not convinced. He notices small details in Moon-jae's behavior and appearance that remind him of the other man. Sun-yong asks Moon-jae why he is still pretending to be someone else when the impostor is supposedly dead. He points out that Moon-jae cannot even be completely certain that he is the real Je Moon-jae. Sun-yong's accusation forces Moon-jae into another confrontation with the truth. The detective cannot prove in court that Moon-jae is lying, but he recognizes that the story does not fit together. He understands that Moon-jae has spent his entire life taking places that belonged to other people and that the identity dispute is far more complicated than a simple case of impersonation. Moon-jae nevertheless survives the immediate legal danger. He is able to continue living under the name Je Moon-jae, while Yu-min is presumed dead after falling into the sea. On the surface, it appears that Moon-jae has finally won. He has his home, career and public identity back. Noja's story takes a different direction. Moon-jae meets him after the confrontation and discovers that Noja's arm has been permanently damaged. Noja refuses to accept money from Moon-jae and tells him that he has decided to retire from the violent life he has lived for years. He returns to his family and begins helping with agricultural work, accepting that his criminal past has finally come to an end. Moon-jae tells Noja that he wants them to stay in touch because Noja is the only real friend he has. Noja rejects the sentimental idea that they are friends, but his actions throughout the series make it clear that he cares about Moon-jae. Before they part, Noja warns him that Seung-gyu will continue hunting him because of the money still owed and tells him to stay hidden. Sun-yong also begins confronting his own failures. During a mediation hearing, he admits that he has failed his wife and children and asks for another opportunity to rebuild his family. Unlike Moon-jae, who continues protecting the identity he has constructed, Sun-yong chooses to accept responsibility for his past and try to create a new life honestly. Moon-jae eventually returns to his apartment and discovers a manuscript connected to the second volume of The Rat. The document appears to be a confession describing the crimes and the truth behind the identity theft. At first Moon-jae thinks it could finally be the proof that he needs to establish himself as the real Je Moon-jae. Then he reads the manuscript more carefully and realizes the opposite. The manuscript contains evidence that could prove that he is The Rat. It reveals the crimes, the stolen writing and the history that connects him to Yu-min and Min-yeong. If the manuscript is published, Moon-jae's entire literary career and public identity could collapse. Moon-jae understands that the trap has never truly ended. Even though Yu-min is gone, the truth he left behind remains inside Moon-jae's own home. The stolen identity, stolen writing and buried memories can still destroy the life Moon-jae fought so hard to protect. The finale then shifts into a disturbing psychological ending. Moon-jae begins writing and rewriting the story in his mind, trying to separate dreams from reality. He remembers the events surrounding the fire, his childhood identity and the transformation that allowed him to become Je Moon-jae. The line between the person he believes himself to be and the person he actually was begins to disappear. Finally, someone starts pounding on Moon-jae's apartment door. Moon-jae becomes terrified and assumes that someone has come to expose him. The voice outside belongs to Seung-gyu, who has returned to demand the money Moon-jae still owes. Moon-jae realizes that even after everything, the criminal world has not forgotten him. Episode 10 closes the series on an intentionally unsettling note. Moon-jae may have survived, reclaimed the name Je Moon-jae and escaped legal punishment, but he has not escaped the truth. Yu-min's manuscript remains a threat, Sun-yong still doubts his story, Noja has walked away from their dangerous partnership, and the stolen identity continues to imprison Moon-jae psychologically. The final meaning of Mousetrap is therefore revealed: Moon-jae spent the entire series believing that he was the victim trapped by The Rat, only to discover that he had already built his life from another person's stolen identity. The real trap was not simply created by Yu-min. It was created by Moon-jae's own lies, jealousy, guilt and desire to become someone else. He may have escaped the physical trap, but he remains trapped inside the identity he spent his life constructing.
