Episode 6 of *My Youth* opens with a fleeting flashback—Hae accidentally overhears a heated exchange between Je-yeon and her colleague. Tensions escalate when the colleague turns physically aggressive, prompting Hae to step in and intervene. Just as the altercation reaches its peak, CEO Pil-do bursts into the scene, taking in the chaos. His eyes widen in realization as he connects the dots, recognizing Hae as the enigmatic author behind the book they're adapting into a film.
Later, Je-yeon finds herself behind the wheel, offering driving lessons to Seok-ju, who seems to be on a perpetual collision course with failure in his attempts to pass his driver’s license tests. Meanwhile, Hae receives a nostalgic gift from his father—a childhood photo album that instantly transports him back in time. As he pores over the faded snapshots, a mischievous idea strikes him, and he enlists Seok-ju's help to sneak the album back into his house unnoticed.
Simultaneously, Tae-rin sits down with Pil-do for a crucial meeting regarding her contract renewal. Her words carry a subtle undertone, hinting at the possibility of her bidding farewell to the company. Post-meeting, fate throws her and Seok-ju together, sparking a heated argument. Tae-rin accuses Seok-ju of harboring hidden agendas beneath his seemingly altruistic facade. Frustration boiling over, she seeks solace and ends up at Hae’s quaint flower shop.
A series of events unfold as Hae undergoes a health check-up, followed by a tech-savvy mission to assist Seok-ju with his new sound system. The duo tiptoes around, trying their best to steer clear of Seok-ju’s mother. Amidst this, their ears catch whispers of a long-forgotten connection between their parents—a tale of past entanglements that led Hae’s father to the island and eventually down the aisle with Pil-do. Yet, despite the revelation, the strained dynamics persist, with Pil-do's overbearing demeanor remaining an unyielding presence.
Later, Je-yeon pays a visit to Hae's home, as the producer's daughter has an appointment scheduled to meet with him. Following their encounter, they bid each other farewell at the company office, where Je-yeon now faces suspension due to the earlier uproar she caused. With an unexpected stretch of free time stretching out before her, she decides to drop by Director Han-na's office, only to find Tae-rin there as well, creating an unexpected convergence of characters.
Meanwhile, Hae seeks solace by the beach, where memories of his mother wash over him like the gentle waves caressing the shore. In a fleeting flashback, we are given a glimpse into a pivotal moment from his past—a doctor's visit where he was diagnosed with Amyloidosis, a condition that casts a shadow of uncertainty over his future, threatening to claim his life at any moment, be it in the near or distant future, with no definitive timeline.
Upon Hae's return home, he is taken aback to find Je-yeon waiting for him, her presence a beacon of unexpected warmth. Having finally reconciled with her own emotions, she musters the courage to confess her love to him, her words hanging in the air like a delicate promise as the episode draws to a close, leaving viewers on the edge of anticipation.
