Episode 10 of "Pump Up the Healthy Love" kicks off with the entrance of a novel client seeking a consultation, specifically requesting Do Hyeon-joong's expertise. However, their encounter takes an unexpected turn when Rosa and Mi-ran discover an array of covert cameras concealed on his person. The client, accusing Hyeon-joong of murder, prompts a swift chase that ends in his departure.
A poignant flashback transports us to Kang Sol's funeral, where Hyeon-joong stands unresponsive to tears, surrounded by reporters who sensationally accuse him of Sol's demise due to excessive exercise regimes he prescribed. Amidst the scrutiny, Hyeon-joong mysteriously vanishes.
In the present, Mi-ran's persuasive prowess convinces the rest of the team to grant Hyeon-joong some breathing space. United, they resolve to keep the gym operational around the clock, with all members diligently working to ward off reporters and Sol's avid fans.
Mi-ran's longing for Hyeon-joong intensifies, leading her to revisit the spots where he once guided her through her fitness struggles. She confides in Ji-ran, revealing that her search is not fueled by worry but by a profound sense of missing him.
Adding fuel to the fire, the landlord informs Rosa of a lucrative offer doubling the current rent, insisting that they vacate the premises. When Rosa catches Roy in conversation with the landlord, she jumps to the conclusion that he's orchestrating their eviction. Her frustration boils over, and she confronts Roy, warning him not to underestimate Hyeon-joong's worth.
Back at the gym, Alex reveals to Seong-im that Hyeon-joong had been his savior in a life-or-death situation. Later, as fate would have it, Alex encounters a group of gossiping students, who claim that Hyeon-joong advised Sol against undergoing chemotherapy, branding him a murderer. Fuelled by rage, Alex grabs a wrench and lunges towards them, intending to confront them head-on!
As Mi-ran wraps up her workday, she spots a figure resembling Hyeon-joong in the distance. Driven by curiosity, she trails him, even scaling ten floors on foot, to uncover his whereabouts. To her astonishment, she discovers him working as a deliveryman. Despite her earnest pleas for him to return to his old life, he remains unmoved by her words.
Alex and Rosa find themselves at the police station, where Alex faces repercussions for his impulsive actions against the students. Though he hadn't physically harmed them, he had angrily dismantled their bicycles in a fit of anger. To Rosa's amazement, Alex's mother arrives with a lawyer to shield him from legal consequences. It transpires that Alex hails from a wealthy family and once pursued a medical degree before switching careers to become a trainer.
Hyeon-joong finds himself longing for his days as a trainer, but the memory of Sol serves as a stark reminder, steering him away from that path. Meanwhile, Rosa breaks the news to the gym members that Hyeon-joong harbors no intention of returning, inciting their wrath. Seong-im's fury knows no bounds, prompting her to seek the media's attention.
Elsewhere, Ji-ran finds herself hospitalized with pancreatitis. In an unexpected twist, Dan makes a surprise appearance, inquiring about her wellbeing. He confesses that he ended their relationship because he was drafted into public service, a commitment that would keep him occupied for extended hours. Believing that Ji-ran couldn't endure such a long separation, he made the painful decision to break up with her.
Mi-ran proceeds to place an array of delivery orders, her quest culminating in a reunion with Hyeon-joong. Seeking to soothe his battered heart, she offers him tteokbokki, albeit an overly fiery variety that nevertheless elicits a genuine smile from him. After devouring the spicy treat, Mi-ran gently reassures him that Sol's demise was in no way his fault.
At this poignant juncture, a YouTube video surfaces, billed as an exposé but actually showcasing the gym members' heartfelt testimonials extolling Hyeon-joong's kindness and dedication to his clients. Alex shares his harrowing tale of failed medical aspirations leading to binge eating, weight gain, and even a suicidal attempt thwarted by his own girth snapping the rope. Hyeon-joong's timely intervention, where he encouraged Alex to workout, slim down, and restart his life, emerges as a pivotal psychological turning point that reignited Alex's will to live.
As Hyeon-joong watches the video, his emotions bubble over. Upon returning to the gym, he's warmly embraced by his peers. However, a fresh dilemma presents itself when the landlord arrives with Alex's mother as the new tenant. Intent on steering Alex away from the gym and towards a more prestigious career, she buys the property outright. Despite Alex's earnest attempts to convey his contentment, his mother remains unmoved.
Elsewhere, Ji-ran confronts Dan at his post, accusing him of insufficient trust. His silence sends her storming off in frustration. Meanwhile, Rosa seeks forgiveness from Roy for a misunderstanding, revealing that Hyeon-joong had confided in Roy about his impending absence and entrusted him to oversee the gym.
Hyeon-joong decides to relocate back to the gym, his face lighting up upon receiving a notification on his phone. He runs into Mi-ran outside, who has thoughtfully bought more tteokbokki for them to enjoy. Spotting the three gym aunties approaching, Mi-ran whisks him into a narrow alley, eager to keep their meal a private affair. Cramped together, they share an intimate moment, but even after the aunties disappear from sight, Hyeon-joong playfully insists they're still around, prolonging their close proximity.
