DNA Lover Episode 6 seamlessly resumes where our hearts left off, with So-jin's chance encounter with Gang-hun by the serene Han River, and Yeon-u's intriguing telepathic rendezvous with Mi-eun atop a towering structure. Gang-hun's bewilderment at So-jin's ire towards him for his unexpected appearance is palpable. He was merely indulging in his solitary late-night jog, unaware of her presence, yet fate intervened as he heroically saved an elderly woman from a scooter's path, earning So-jin's swift first aid assistance.
Meanwhile, Mi-eun finds Yeon-u's attempt at telepathic communication with So-jin both endearing and bizarre. In a subtle ploy, he lingers near a restaurant close to So-jin's abode, feigning a misunderstanding about their meeting spot, all while A-ri catches him surreptitiously snapping a photo. His attempt to relay the image to So-jin falters due to the fickle nature of network connections.
Later, Yeon-u joins his mother and aunt for a dinner laced with hope. His mother's heart yearns for her husband's return, believing he will abandon his infidelity and reclaim their love.
As the dawn breaks, Jung-tam embarks on his telepathic experiment with Sumg-mi, fervently transmitting his longing to see her. His conviction stems from Sung-mi's persistent appearances, as if drawn by an unseen force. His chance encounter with Gang-hun leads to a discussion about Yeon-u's relentless pursuit of So-jin's affections, further fueling Gang-hun's anxiety. Amidst this emotional turmoil, Gang-hun's paths continue to cross with Mi-eun, weaving an intricate web of emotions and desires.
Elsewhere, Sojin delves into the mystery of why Yeon-u failed to reach the Han River, convinced that a misunderstanding or a crossed signal must have occurred. She ponders over whom Yeon-u might have encountered at the tower and whether he inadvertently misheard the designated meeting spot. Reaching out to him, she finds herself engaged in a conversation that teeters on the brink of rescheduling their plans. However, Sojin's calendar remains packed, even on a Saturday, leaving Yeon-u disheartened as he had eagerly anticipated their reunion.
Meanwhile, A-ri purchases two potato skewers, contemplating deeply before embarking on a journey to the church. With a potato skewer in hand, she approaches Father Andrea, intending to offer him a taste. But her courage falters upon witnessing him in an intense conversation atop the roof, seemingly urging someone towards repentance, his words echoing mysteriously against the night sky. Returning home, A-ri confides in Sojin about her growing admiration for the priest.
Elsewhere, Mi-eun's encounter with an old friend takes a sour turn, as her polyamorous lifestyle becomes a subject of contention. Fortunately, Yeon-u, who happens to be present, steps in to offer solace. Over drinks, they share their past, revealing that Mi-eun had inexplicably vanished from Yeon-u's life for six months. Mi-eun inquires about the nature of their relationship during that time, and Yeon-u admits he found comfort in their distant bond. He encourages her to stay true to herself, undeterred by societal criticisms.
Yeon-u, filled with excitement, calls Sojin to invite her to a celestial spectacle on Sunday. Enthralled by the prospect of stargazing, Sojin eagerly accepts, and their conversation quickly shifts to meticulous planning for their camping adventure. In the midst of their preparations, Sojin reaches out to Gang-hun, seeking a favor while casually mentioning her impending camping trip with Yeon-u. Gang-hun's surprise is palpable, particularly after Sung-mi's recent mention of glamping spots resembling luxurious hotels, adding an unexpected twist to their humble outdoorsy plans.
He hurries to the campsite, intruding on Yeon-u and So-jin's intimate moment, their playful antics only serving to irritate So-jin further. As if orchestrated by fate, Mi-eun catches sight of Gang-hun and attempts to trail him, only to lose her way amidst the confusion. Gang-hun, summoned back to duty with a terse call, reluctantly departs, leaving behind a stern warning to Yeon-u: he will not tolerate any harm coming to So-jin through their relationship.
With Gang-hun's departure, the heavens seem to align as Yeon-u and So-jin indulge in a celestial spectacle, their eyes glued to the starry expanse. Yeon-u's curiosity prompts him to inquire about So-jin's earnest fascination with telepathy, and she confides that she yearns to instinctively sense her lover's pain, ready to alleviate it with her very being. As they nestle closer, listening to the soothing melodies of So-jin's MP3 player, which Yeon-u had miraculously repaired, their bond deepens.
However, the idyllic moment is shattered by the unexpected arrival of Mi-eun, who boldly introduces herself as Yeon-u's former flame. Jealousy flickers within So-jin, while Mi-eun is left bewildered by Yeon-u's sudden disappearance from their circle, only to resurface with So-jin under the stars.
Meanwhile, Gang-hun's team battles a blaze at a random flower shop, where a familiar logo on one of the pots echoes the mysterious gift bestowed upon Yeon-u. This coincidence sparks intrigue, casting suspicion on the new woman in Gang-hun's father's life. Could she be orchestrating something behind the scenes?
Post-camping, Yeon-u delves into Mi-eun's television appearances, seeking the key to winning So-jin's heart. On the other hand, So-jin finds herself consumed by thoughts of Mi-eun, her mind racing after learning of their chance encounter at the tower. Her digital stalking leads her to a photograph of Mi-eun's mother, adding yet another layer of complexity to this tangled web of emotions.
She remains blissfully unaware that Yeon-u is intricately weaving a web of coincidences around their lives, meticulously planning each thread. He cunningly enlists the aid of Jung-tam, tasking him with shadowing So-jin and orchestrating yet another experiment designed to draw them closer.
However, fate takes an unexpected turn when Jung-tam's pursuit of So-jin is abruptly halted by the theft of his wallet on the bustling subway. In a twist of fate, Sung-mi swoops in like a guardian angel, rescuing him from the predicament. Their encounter leads Jung-tam astray, ultimately leading him to stumble upon the aquarium where chance introduces him to Mi-eun.
Meanwhile, So-jin finds herself at the exhibition, her heart heavy with the realization that her attempts to telepathically connect with Yeon-u have fallen flat. But just as despair begins to creep in, Yeon-u appears out of nowhere as she exits the exhibition, sending her heart soaring with amazement. Convinced that they've indeed communicated on a spiritual plane, she joyfully accepts his invitation for their very first official date.
