Miraculous Brothers

The discovery of skeletal remains and a student card with Lee Ha-neul's name at Sopyung Lake marks a significant shift in the investigation. Kang San is heartbroken, fearing the loss of his brother. Meanwhile, Hye-kyung becomes suspicious of Tae-man's attention towards the boy living with Dong-ju. Acting as if she is unfamiliar with the boy, Hye-kyung accepts Kang San's picture from Tae-man but immediately visits Dong-ju's house, bringing a mysterious gift.

As the police approach the truth, Lee Tae-man's discomfort grows, causing him to make rushed mistakes. Dong-ju uncovers news of Byun Jong-il's death and holds himself responsible for failing to elicit a confession regarding his father's murder. Meanwhile, Kang San finally meets his brother and comprehends why Ha-neul is adamant about keeping Kang San away. At the same time, Dong-ju has his own agenda to finalize things definitively.

Dong Ju drops a bombshell during a TV show, bringing to light all the concealed facts related to Lee Tae-man and others, including his own undisclosed matters. This disclosure causes a shift in the investigation, prompting individuals previously deemed unlikely to cooperate to come forward voluntarily for interrogation by the police. Meanwhile, an individual approaches Kang San with the demeanor of a guilty party, earnestly seeking forgiveness.

Kang San is regretful for losing control and causing harm to Dong-ju. Dong-ju reassures him that he's fine, but he expresses concern about his recent instability. Meanwhile, the police are on the verge of apprehending Lee Tae-man and Choi Jong-nam, but their window of opportunity is closing rapidly. Byung-man pays a visit to Chang-geun, expressing remorse for not giving more attention to the young individual who sought his help 27 years ago.
