Culture critic and Baeksang Arts Awards judge Jeong Deok-hyeon, writing for Ilgan Sports, praised the series for its profound focus on the "post-event" lives of victims. He noted that it effectively portrays the isolation of those whose time has stopped due to tragedy, while the rest of the world continues to move on indifferently, and emphasized the "wonderful" solidarity between characters who share similar wounds. He specifically lauded Cha Eun-woo's high-caliber range of expression in portraying Kwon Seon-yul, highlighting his exceptional ability to effectively convey the complex, layered emotions of a character navigating the duality of being both a victim and a potential perpetrator. Jeong noted that Cha captures the character's internal conflict with such precision that it makes Seon-yul’s dark and secretive nature feel "vividly human" and deeply grounded.
South Korean media outlets emphasized the powerful and sophisticated performances of the lead cast. Herald POP praised Kim Nam-joo's "passionate emotional acting," highlighting her ability to convey profound sorrow in scenes such as her character wailing at her son's grave after her release from prison. Writing for Sports Chosun, Moon Ji-yeon described Kim Nam-joo's portrayal as demonstrating "insane acting skills," citing the heart-wrenching scene of a mother wailing over her child's death and her decision to take direct action against the perpetrator. Moon described her performance as an "explosive and raw" portrayal of devastated motherhood, emphasizing her ability to sustain immense emotional tension throughout her pursuit of personal justice.
Moon Ji-yeon similarly praised Cha Eun-woo’s absolute immersion into the role, highlighting his expert portrayal of "unfiltered anger" and a "rough, unrefined lifestyle." She emphasized his mastery in handling physically demanding and high-tension scenes, labeling him a "breathtaking ending master" for his acting ability to command the screen and dictate the narrative’s tension through subtle facial shifts during pivotal cliffhangers. Meanwhile, Star Today noted that Cha's "intense eye acting" and natural charisma were central to the show's immersion. Critics highlighted his technical skill in using his gaze to communicate a spectrum of complex psychology—from a hollow desolation to sharp hostility—effectively telling the character's tragic backstory and hidden depth without the need for extensive dialogue.
Internationally, the lead performances were lauded for their weight and authenticity. Hidzir Junaini of NME commended Kim Nam-joo’s portrayal of Soo-hyun, calling it "powerful". Pierce Conran of the South China Morning Post described Cha Eun-woo’s portrayal as "gritty and raw," praising the "nuanced and melancholic" energy he brought to the screen while holding his own against Kim Nam-joo’s "towering" performance. Rolling Stone India further observed that his acting effectively captures "complex, layered emotions," proving his prowess as a dramatic actor in an atypical narrative. Reviewing for Bollywood Hungama, the series was described as an "intriguing" mystery thriller, adding that the lead actors carry the narrative with compelling performances that maintain tension through unpredictable twists.
The series received high ratings from the media. But Why Tho? awarded the opening episodes a 9.5/10, praising the "visceral and captivating" performances, while OTTplay gave the drama a 4/5 rating, stating that both lead actors "shine" in the emotionally charged thriller. It also maintained a high user rating of 9.0/10 on IMDb, attributing its popularity to a "solid narrative" and "flawless performances" that enhance the mystery elements. Furthermore, viewers on MyDramaList described the series as a "perfectly captivating" and "must-watch" masterpiece, highlighting its emotional depth and suspenseful storytelling.

Cha Eun-woo solidified his status as a "buzz icon," as video content showcasing his acting transformation surpassed 10 million cumulative views across various platforms. Additionally, he secured the top spot in the "drama search issue keywords" category, while the series itself and Kim Nam-joo ranked second and fifth, respectively.
