The following dawn, the team gears up for their journey to the Athlete's Village, where rigorous training awaits. Gun, reluctantly bidding farewell to Cola at a pet care facility, struggles to conceal his heartache at the temporary separation.
At the orientation, tensions rise as the coach's patience wears thin with Shin's incessant grumbling about Sae-yan and Shi-on's tardiness. He issues a stern warning, threatening to expel them should they continue to disrupt the training regimen with such infractions.
Meanwhile, Ju-yeon finds herself in a predicament, attempting to steer clear of Gun's path yet their encounters seem inescapable, leaving her flustered and discomposed. Shin, noticing her evasive behavior, is intrigued but his attention is diverted by the sight of Sae-yan and Gun spending time together, fueling his fears of the resurfacing of painful memories.
Elsewhere, chaos ensues at Mrs. Kyung's residence as Sae-yan's bodyguard arrives unannounced. Unable to reach her by phone, the nephew frantically translates her whereabouts to the anxious guard.
Shin, determined to dissuade Sae-yan from pursuing her athletic endeavors, paints a grim picture of the Athlete's Village, likening it to a military camp where she'll be constantly confronted with his displeased visage. However, Sae-yan finds amusement in his discomfort, viewing it as a challenge she's unwilling to relinquish, thus vowing to continue her journey undeterred.
On D-Day's dawn, Shin and Gun vied fiercely, each offering their sleek cars to Ju-yeon as a means to the Athlete's Village. Their bickering filled the air with tension, yet Ju-yeon's choice fell upon Shin, his smirk broadening as he basked in victory's glow. Little did he know, Ju-yeon's heart raced solely because of her proximity to Gun, her true desire.
Just as the dust settled, Sae-yan arrived, making a bold declaration that she and Ju-yeon would accompany Gun. This unexpected turn had Shin fretting over the prospect of Gun and Sae-yan sharing a ride, ultimately compelling him to cram everyone into his vehicle. Amidst the chaos, thoughts of Cola lingered in his mind, only to reveal later that Gun had entrusted her to their parents' care.
As they prepared to embark, the bodyguards materialized like shadows, casting an ominous shadow over their plans. Sae-yan, swift and decisive, shoved Ju-yeon and the Lees into the backseat, piloting the car with reckless abandon in a bid for escape. Gun's arm encircled Ju-yeon, her anxiety mingling with her growing feelings for him. She feigned slumber, her mind racing as Gun puzzled over Sae-yan's reluctance to return home. On the verge of confiding her quest for the enigmatic man, Shin's interruption shattered the moment.
At the hospital, Dr. Han sought a subtle sign of Nurse Song's affection. Her laughter at his cheesy group chat messages and willingness to dine at his suggested restaurant filled him with joy. As he settled the bill, his colleagues mischievously teased the pair, fueling rumors of a budding romance. Nurse Song's remark, comparing Han to her father, left him reeling with disappointment.
The rest stop became a stage for Shin's maneuvering, as he shooed everyone from the car before secretly contacting Sae-yan's father with their whereabouts. Mistaking Ju-yeon for Sae-yan asleep in the rear, Shin drove off, convinced he'd left Sae-yan with Gun. The revelation that Ju-yeon and Gun were, in fact, calling from the rest stop left him flabbergasted, forcing an impromptu detour to the nearest resort.
Sae-yan, convinced of a sinister plot to oust her, engaged in a heated confrontation with Shin, their spat escalating until he accidentally shattered her bracelet. The sight of her storming off filled him with regret, the aftermath of their altercation echoing through the air.
As Ju-yeon and Gun traverse the path towards the resort, their steps echoing in the serene surroundings, she snaps at him, her voice laced with frustration as her feet bear the brunt of their journey, bleeding and aching. Yet, Gun remains unfazed, his heart brimming with tenderness. He cleverly coaxes her with her beloved snack, a sweet bribe to distract her as he gently disinfects her wounds, their shared laughter filling the air with a moment of unexpected sweetness amidst her tears.
Meanwhile, at the resort's sprawling parking lot, Shin tinkers with the bracelet, eyes glued to the entrance, anxiously awaiting Sae-yan's return. But fate seems to have other plans as she wanders off, lost in the labyrinth of unfamiliarity. Shin, with a mischievous glint in his eye, concocts a ruse, pretending to need the privacy of nature's call, only to secretly dial her father's number. Suddenly, a sharp pain shoots through him, his imagination conjuring up a serpent's bite on his back, a supposed punishment for his ill-conceived plans. He apologizes profusely, convinced it's karma's way of settling scores.
With a heavy heart, he presents her with the bracelet, a revelation that he knows the enigmatic figure she seeks, stunning her to silence. Her revelation that he's aware of her true father's identity stirs confusion in him, just as he succumbs to the weight of his actions, collapsing in a faint. Sae-yan, desperate to aid, attempts to extract the imagined venom, but the timely arrival of the ambulance dispels the illusion—it was merely an allergic reaction all along.
The scene is one of chaos and confusion as Shin and Sae-yan grapple with the aftermath, their emotions raw. Ju-yeon and Gun's arrival adds to the commotion, their own troubles looming large as they discover their vehicle's gas tank is empty. But just when all hope seems lost, Shi-on appears like a knight in shining armor, saving the day with his timely intervention.
As the cast of players embarks on their journey to the training grounds, Gun leads Ju-yeon to a bridge, hallowed by memories of his first love's rescue. His confession flows like a gentle stream, but Ju-yeon's heart, though touched, remains steadfast in its refusal. Gun, a keen observer of emotions, sees through her façade, urging her not to deny her true feelings. And as the final frame of Bad-Memory Eraser's Episode 10 unfolds, their lips meet in a kiss that speaks volumes of the complexities and beauty of human connections.
