Episode 5 of "Jack & Joker: U Steal My Heart" kicks off with a dramatic entrance by Joke at Aran's suite, only to be met with a brutal confrontation orchestrated by Hope and his henchmen. Amidst the chaos, Jack's ring is uncovered, serving as a damning piece of evidence for Hope, who promptly summons Jack, flaunting a battered Joke as proof. Hope's order is unwavering: retrieve the necklace, come what may. Joke, ever the strategist, concocts a cunning plan.
The necklace, a coveted item in an underground auction, poses a unique challenge. With the auction staff's familiarity with Joke's criminal past, Aran is reluctantly tasked with infiltrating the event as a billionaire persona. His reluctance melts away when Hope reminds him of the dire consequences of crossing Boss.
Later, under the guise of camaraderie, Jack discovers Joke nursing his wounds in solitude. As Jack tends to his injuries, Joke utters a heartfelt apology for embroiling him in the turmoil. A moment of vulnerability ensues when Joke hesitates to lift his shirt, eliciting a wry smile from Jack. Meanwhile, Hope shares a tense exchange with Save, who expresses her concern for both him and Jack, promising that all will be well. Their verbal sparring ends with Save's solemn warning: don't die.
The auction day arrives, and Jack and Hope accompany Aran, disguised as his bodyguards. Aran's impatience clashes with Jack's impromptu maneuvers, threatening to unravel their plan. But fate intervenes when Rose unexpectedly arrives, her rivalry with Aran palpable. She begrudgingly invites him as her guest, while Jack, donning a mask, prays for anonymity.
The auction unfolds in a dazzling display of extravagance, and the group's eyes widen as Aran's necklace makes its appearance. A poignant revelation follows: the necklace belonged to Alice Morakot, Aran's mother and a beloved actress, who passed away wearing it. The secret of her connection to Boss remains hidden.
Aran's competitive streak surfaces, bidding recklessly until the price soars to 30 million, forcing him to relinquish. In a desperate attempt to restrain him, Jack's mask slips, exposing his identity to Rose. He flees, pursued by Aran and Hope.
Their next move hinges on Joke stealing the delivery truck carrying the necklace to Rose. However, a roadblock arises—Joke can't drive. Hoi's frustration mounts as he struggles to teach Joke, who refuses to risk Hoi's life by having him accompany him. Their banter turns philosophical, with Joke confessing his preference for a kind and forgiving partner, while Jack finds himself unwittingly smiling at the confession.
The following day, Joke transforms into a bearded, menacing driver, but his disguise proves less than seamless as Gui, the auction's vigilant guard, accompanies him. Amidst the chaos, Tattoo's cunning plan unfolds—a sleeping potion disguised as air freshener. Joke feigns unconsciousness, leaving Aran momentarily alarmed before secretly chuckling at the elaborate prank.
As they retreated to the truck, the air freshener's sluggish effect left Gui perilously close to suffocating Joke before succumbing to unconsciousness. Jack's concern lingered, yet when Joke pondered if his safety was the priority, Jack's response was stark: the mission's success outweighed all else.
Arriving at the designated meeting spot, Joke was confronted by the auction's vigilant guards, their recognition instant. Jack and the team's subsequent arrival sparked a fierce confrontation. Aran, Hoi, Tattoo, and Hope were felled, but Jack and Joke, their synergy unbreakable, vanquished the guards. Despite being stabbed in the fray, Jack urged Joke to flee, a suggestion Joke adamantly refused. Rising from the fray, Joke's attention was drawn to Tattoo's hasty retreat, the necklace in his possession.
Outside, Tattoo dialed the police and prepared to depart, only to be confronted by Hoi, who threatened to sever ties if he didn't desist. Tattoo acquiesced, but their friendship lay shattered. Racing to his mother, Tattoo revealed the necklace, his dreams of a better life shimmering. Yet, she implored him to return it, refusing to emulate the corrupt wealth of its former owners.
Meanwhile, Joke tended to Jack's stabbing wound before staking out Tattoo's apartment. When Tattoo appeared, feigning innocence, claiming he'd found the necklace by chance and intended to restore it, Joke silently accepted the lie, his compassion evident. Tattoo, overwhelmed with guilt, expressed his gratitude to Joke for everything.
Jack was deeply moved by Joke's capacity for forgiveness, despite Tattoo's repeated betrayals. They entrusted the necklace back to Aran, who deemed the matter settled and chose to overlook the remaining missing pawned items. Inspired by Aran's magnanimity, Jack extended the same olive branch to Joke, requesting a fresh start. Joke's delight was palpable as Jack invited him to share a meal with Grandma.
On the other end, Rose's fury boiled over at the disappearance of her necklace. The host presented Jack's photograph, identifying him as one of the perpetrators. It seemed Rose had been on his trail since the night he rescued her. As Episode 5 of Jack & Joker drew to a close, her advisor, Nang, revealed a troubling truth: he'd been colluding with a loan shark to settle his debts. If Rose desired to aid Jack, she must now pay off that debt herself.
