Dive Into You Episodes 9-10 Deliver Plot Twists and Betrayals

With two episodes remaining in its broadcast run, “Dive Into You” is navigating toward its conclusion through a series of escalating revelations that reshape character arcs and shatter viewer assumptions about the central time-travel mystery. The drama follows Yoon Ha Na (played by Kim Ji Yeon) and her sister Yoon Ha Ru (Jang Se Hyuk) as they attempt to alter the fate of Jung Woo Jae (Park Seo Ham) by using a camcorder that allows them to travel through time. Episodes 9 and 10 bring multiple turning points that, according to Soompi, delivered several moments compelling enough to make viewers react intensely to the screen.

Lee Hyeong Won’s Unexpected Redemption

From Public Enemy to Misunderstood Hero

The character of Lee Hyeong Won (Kim Han Yeong) entered the series under a dark cloud. Audiences learned in earlier episodes that he had attacked Jung Woo Jae in the original timeline, positioning him as a central antagonist to the show’s core trio. However, as his backstory unfolded, the character gained layers. Lee Hyeong Won’s origins as an orphan striving to build a career in judo created sympathy among viewers despite the weight of his past actions. This contradiction left audiences in an uncomfortable position: they were beginning to care for a character they knew was destined to become a villain.

The Twist That Saved a Character Arc

Episode 8 delivered the pivot that altered Lee Hyeong Won’s trajectory. The revelation that Yang Jun Mo (Kang Hyung Suk), not Lee Hyeong Won, was the man in black who destroyed the camcorder created an opening for redemption. Then in episode 9, Jung Woo Jae reveals to Yoon Ha Ru that he and Lee Hyeong Won have actually become friends in this timeline after the man-in-black incident. The friendship did not form by accident—Jung Woo Jae’s trust in Lee Hyeong Won, combined with Yoon Ha Ru’s encouragement for him to continue pursuing judo, has allowed the athlete to build a future beyond the cycle of revenge that consumed him in earlier timelines.

Why This Arc Matters

According to Soompi, this redemption carries particular weight because it represents the indirect positive consequences of Yoon Ha Na and Yoon Ha Ru’s efforts to save Jung Woo Jae. A character who once seemed locked into a tragic role has been given a path toward genuine change. The transformation rests not on Lee Hyeong Won’s own actions in this timeline, but on the structural changes the twin sisters have created by altering the circumstances around him.

Yang Jun Mo Exposed as the Stalker

At the beginning of episode 9, the twins operating from the present day make a critical discovery: Yang Jun Mo has been the stalker targeting Yoon Ha Na all along. They uncover evidence by stealing his bag and accessing his laptop, where they find digital diary entries filled with references to Yoon Ha Na as “my little canary.” These entries confirm his obsession, but they present an immediate legal problem. Because Yang Jun Mo never uses her actual name in his writings, the diary alone cannot be submitted as court evidence. The twins are forced to pursue a different strategy, returning once again to the past through the camcorder to attempt intervention at an earlier point in time.

The Script That Never Was

In this previous timeline, set in the late 2010s, Yang Jun Mo seeks to involve Yoon Ha Na in his latest film project, pressuring her to take the female lead role. In the original version of events, she accepted and the decision ultimately led to her breakup with Jung Woo Jae. Armed with knowledge of Yang Jun Mo’s true nature, Yoon Ha Na attempts to break the pattern by rejecting the role entirely and suggesting he cast a more established actress instead. The plan appears to be working until Yang Jun Mo insists she get into his car.

The Moment Fans Question Everything

According to Soompi, this is where the drama crossed into territory that prompted significant viewer frustration. Yoon Ha Na, fully aware that Yang Jun Mo is her stalker and poses a genuine threat to her life, chooses to enter the vehicle anyway. When Yang Jun Mo subsequently drives recklessly through traffic, his explanation that he was not in control of his actions seems to satisfy Yoon Ha Na, who accepts his account without pursuing any legal recourse, filing a restraining order, or taking protective measures. The gap between what the character knows and what she does created what Soompi describes as a deeply frustrating narrative moment.

The Cycle of Violence Around Lee Hyeong Won

The reveal of Yang Jun Mo’s true role as stalker and antagonist exposes a pattern across timelines. In the original sequence of events, Yang Jun Mo hired Lee Hyeong Won to kill Yoon Ha Na. Lee Hyeong Won, consumed by his belief that Jung Woo Jae had destroyed his judo career, attacked the wrong person and killed him instead. In the subsequent timeline, the arrangement repeated, with Jung Woo Jae dying in the crossfire of an assassination attempt meant for Yoon Ha Na. In the current timeline, the friendship between Jung Woo Jae and Lee Hyeong Won should have eliminated Yang Jun Mo’s leverage. Lee Hyeong Won no longer harbors animosity toward the man he now considers a friend, so the manipulation that worked before should fail.

Yet when Yoon Ha Ru informs Jung Woo Jae about the car incident and requests that he check on Yoon Ha Na, the errand puts Lee Hyeong Won directly in harm’s way. He is attacked by someone who appears to have been hired by Yang Jun Mo. Lee Hyeong Won, who has done nothing wrong in this timeline except assist a friend and pursue his athletic career, finds himself injured and facing potential damage to the judo future he is just beginning to rebuild.

The Destruction of the Camcorder

Episode 10 introduces what Soompi characterizes as the most infuriating development of the entire series. Jung Woo Jae, now aware of both the time-travel mechanics and the fact that Yoon Ha Na abandoned her acting career specifically to save his life, responds by taking Yang Jun Mo’s side in a moment of profound miscalculation. After Yang Jun Mo explains the camcorder’s capabilities and hints at the sacrifice Yoon Ha Na has made, Jung Woo Jae destroys the device—the very tool the twins need to continue their rescue efforts.

The action represents a fundamental break in communication between the protagonists. Rather than discussing the situation with Yoon Ha Na, considering their options together, or working toward a collaborative solution, Jung Woo Jae accepts the antagonist’s perspective and sabotages his partners’ plan. According to Soompi’s assessment, this decision stands as the most aggravating moment in the show’s run.

The Remaining Path Forward

With two episodes left to resolve the narrative, Yoon Ha Na and Yoon Ha Ru now face the central question: how will they continue to alter Jung Woo Jae’s fate without the camcorder that enabled their previous interventions? The destruction of the device has created a new crisis beyond simply saving one life. The twins must find an alternative approach, overcome obstacles neither could have anticipated, and navigate whatever remaining timeline shifts are possible. The finale will reveal whether the loss of their primary tool represents an insurmountable setback or whether the changes they have already set in motion have fundamentally altered the course of events in ways that do not require further time travel.
