Piggyback Ride: Episode 4 Unveils Heart-Wrenching Memories and Ignites Viewer Emotions

The Emotional Climax: Episode 4 as a Turning Point
Episode 4 of 'Piggyback Ride' stands as a pivotal moment in the series, delivering what many viewers describe as an 'infinite emotional' experience. The episode begins with a flashback to a critical moment - Ryu Seonjae (played by Byeon Woo-seok) saving Lim Sol (Kim Hye-yoon) from drowning in a reservoir. This scene sets the emotional tone for the entire episode, revealing the depth of their connection and establishing the foundation for their complex relationship.
What makes this episode particularly powerful is how it serves as a climax for the first segment of the story. The writer cleverly structured the narrative to create multiple layers of storytelling - within the overall plot's beginning-development-climax-conclusion structure, episode 4 functions as the climax of the 'beginning' phase. This deliberate construction pulls viewers deeply into the emotional world of the characters, using Seonjae's feelings as the primary emotional anchor.
Dual Perspectives: Seeing Through Seonjae's Eyes
One of the most compelling aspects of episode 4 is how it revisits the reunion scene from episode 1, but this time from Seonjae's perspective. This shift in viewpoint allows viewers to understand two crucial facts: that Sol still doesn't remember him, and that she appears exactly as she was in the past.
This revelation confirms that Seonjae's reunion with Sol is indeed their first meeting in 14 years, adding layers to their complex relationship. The episode masterfully portrays Seonjae's enduring love for Sol, showing how he recognized her voice during a radio call-in segment and how he treasured every encounter with her, even when she didn't remember who he was.
The poignant line that resonates throughout the episode comes when Sol questions: 'What I lost - was it my memories, or was it you?' This moment of clarity marks Sol's emotional breakthrough as she realizes that what she truly lost wasn't just memories, but Seonjae himself - someone she now desperately doesn't want to lose again.

The Accident Sequence: Piecing Together the Past
Episode 4 provides crucial details about the accident that changed Sol's life. We see Sol falling into water with injuries already visible on her face, suggesting she was hurt before the drowning incident. Seonjae also appears injured with a split lip and marks on his neck, hinting that he may have confronted someone while trying to save Sol.
The mysterious glowing of Seonjae's watch during the rescue raises questions about the nature of the time slip and whether Seonjae himself might have experienced something similar. These details suggest that Seonjae's death in the present timeline might not have been accidental but possibly a murder, especially considering his cautious behavior at the hotel.
When Sol returns to 2023 after her time slip, she finds herself at the hospital where Seonjae was taken, rather than at the stream where the time slip occurred. This disorientation adds to the mystery surrounding the mechanics of the time travel in the story.
The Love Triangle: Past Relationships Resurface
The episode delves into Sol's past relationship with Kim Tae-sung (Song Geon-hee), adding another layer of complexity to the story. When 34-year-old Sol in her 19-year-old body encounters Tae-sung, she's shocked to discover their dating relationship and her own aggressive pursuit of him through text messages.
A tense moment occurs when Tae-sung helps Sol after she falls, just as Seonjae approaches to assist her. The laser-like glares exchanged between the two men establish the love triangle dynamic. Despite being Sol's boyfriend, Tae-sung quickly notices that Sol seems different, asking if 'she's back,' suggesting he's perceptive enough to sense the change in her.
This relationship dynamic adds emotional stakes to Sol's journey in the past, as she navigates feelings and relationships that her 34-year-old self has long moved beyond.

Fateful Encounters: The Bus Stop and Reservoir
Some of the most meaningful scenes in episode 4 occur at transportation hubs - places of transition that mirror Sol's own journey between times. When Sol falls asleep on a bus and misses her stop, Seonjae, unable to simply let her go, leaves his father's shop to follow her.
Sol ends up at Juyang Reservoir, a location that triggers a sense of familiarity. This setting becomes the stage for a dangerous encounter when a suspicious taxi approaches Sol, only to be diverted by a drunk passerby. Though saved from one threat, Sol faces harassment from the drunk man until Seonjae arrives running to her rescue.
This sequence culminates in a powerful moment of recognition for Sol, as she realizes that Seonjae was the person who tried to save her during her past accident. The parallel between past and present rescue attempts creates a powerful emotional resonance, reinforcing their connected destinies.
The Revelation: Memories Begin to Surface
The emotional climax of episode 4 comes when Sol begins to recover fragments of her memory, recognizing Seonjae and their shared past. This breakthrough moment transforms the narrative from a story about saving Seonjae's life to a journey of reclaiming lost love and memories.
The episode reveals that memories are precious because of the people we share them with. Sol, who had pushed away her memories to the point of forgetting the people in them, now embarks on a mission to reclaim her past with Seonjae.
The final scene shows Seonjae's perspective during their radio call interaction, revealing that he had deliberately dialed Sol's number rather than it being a random connection. Despite his efforts to reach out, Sol still didn't remember him, leaving Seonjae with undisguised disappointment as the episode concludes.
Viewer Reactions: An Emotional Rollercoaster
Episode 4 generated significant emotional responses from viewers, with many describing it as deeply moving. Online communities buzzed with reactions, with viewers expressing how the episode made them understand why others had described the series as 'touching' despite it initially appearing to be a typical youth romantic comedy.
Viewers particularly praised how the episode built up to reveal the shape, color, and size of Seonjae's feelings for Sol. The emotional impact was so strong that many viewers found themselves binge-watching up to episode 4 in one sitting, unable to tear themselves away from the developing story.
The episode's ability to deliver such powerful emotional impact so early in the series (only 4 episodes in) impressed viewers and critics alike, setting high expectations for the remaining episodes. As the series has continued to air, it has maintained a steady viewership, indicating it has secured a loyal audience base.
Time Slip Mechanics and Future Developments
Episode 4 provides some clues about the mechanics of the time slip, suggesting that Seonjae's watch activates at midnight. Some viewers speculate that the time slip might be driven by Seonjae's unfulfilled love for Sol, creating a supernatural connection between them.
The episode reveals that Seonjae loved Sol since their high school days when she was infatuated with Kim Tae-sung and didn't even know Seonjae existed. This unrequited love, combined with Seonjae's discovery just before his death that Sol was his fan but had no memory of their shared past, might be the emotional catalyst for the time slip phenomenon.
As the series has progressed beyond episode 4, viewers have continued to speculate about the rules governing the time slip and how Sol's actions in the past might affect the future. The shifting timeline and the characters' evolving relationships continue to drive viewer engagement and emotional investment in the story.
