Episode 5 of "The Nice Guy" kicks off with an intense scene where Seok-cheol's menacing boss, Chang-soo, tasks him with eliminating Tae-hoon. After much deliberation and a harrowing nightmare where he envisions himself as Tae-hoon's murderer, Seok-cheol ultimately musters the courage to decline the ruthless order.
Meanwhile, Tae-hoon finds himself enchanted by Mi-young, compelling her, against her will, to serenade him in a secluded room. His actions, though generous financially with a lump sum of money, leave her feeling uneasy and confined until she musters the strength to fight back and secure her freedom.
Upon returning home that night, Mi-young encounters Seok-cheol, who had been eagerly searching for her. She embraces him warmly and inquires about his motives behind severely punishing her school bullies, leading to his expulsion. He responds resolutely, vowing to mete out justice to anyone who dares harm her.
A brief flashback unfolds, revealing Seok-cheol's valiant act of confronting and defeating all her tormentors, steadfastly refusing to implicate Mi-young as the victim.
The following day, Mi-young stands her ground, refusing to perform at Tae-hoon's establishment. This defiant act brings to Tae-hoon's attention the truth about her relationship with Seok-cheol.
Elsewhere, Seok-hee stumbles upon a hidden invitation to an art gallery belonging to Ki-hong, sparking her suspicions that he plans to attend with another companion, considering the lengths he went to conceal the ticket from her.
After bidding farewell to the bustling bar, Mi-young embarks on a journey of street performing, her guitar echoing melodies of hope amidst the urban hum. Meanwhile, Seok-cheol finds himself blocked from securing a loan due to his profession, his refusal to eliminate Tae-hoon having cost him a vital opportunity to repay his sister's debts. Plagued by this dilemma, he crosses paths with Mi-young, their encounter shadowed by Tae-hoon's watchful eyes. The latter lurks in the background, his romantic ambitions clouded by fear that Seok-cheol's reappearance could complicate his plans.
Elsewhere, Chang-soo makes his way to Seok-cheol's father's abode, seeking a way to broker peace with Tae-hoon. With compassion and wisdom, the elder orchestrates a confrontation between the two adversaries. In this tense encounter, Chang-soo expresses a yearning for a fresh start, an olive branch extended in the hope of reconciliation. Yet, Tae-hoon responds with ruthless humiliation, spurning any notion of alliance, his contempt clear and cutting.
Desperate and humiliated, Chang-soo turns to his trusted lieutenant, issuing a grim command: to seek out someone willing to eliminate Tae-hoon. As the episode draws to a close, the stage is set for a darker turn, with revenge whispers filling the air and fateful decisions looming on the horizon.
