Who Are You: School 2015 is a South Korean television series that explores identity, high school bullying, and teenage survival. Directed by Baek Sang-hoon and Kim Seong-yoon, the sixteen-episode drama aired on KBS2 and became a landmark installment in the network's long-running School anthology franchise. The story follows identical twin sisters separated in childhood—Lee Eun-bi, who suffers severe abuse at an orphanage, and Go Eun-byul, who grows up in a privileged adoptive home attending a prestigious Gangnam high school. When Eun-byul vanishes and Eun-bi loses her memory after a suicide attempt, Eun-bi accidentally assumes her sister's identity, setting off a complex narrative of deception and emotional recovery.
The series stands out for refusing to sugarcoat the realities of adolescent social hierarchies, academic pressure, and psychological torment. Rather than treating school bullying as a minor plot device, the show anchors its emotional weight in Eun-bi's trauma and her gradual reclamation of self-worth. Viewers looking to understand the show's cultural footprint, character dynamics, and production background will find a complete breakdown below.
Plot Overview and Twin Identity Switch
The narrative kicks off with a stark contrast between the two sisters. Lee Eun-bi lives at the Love House orphanage in Tongyeong, where she cares for younger children while enduring relentless, vicious physical and psychological bullying from classmates led by Kang So-young. Exhausted by systemic institutional neglect and abuse, Eun-bi jumps off a bridge to end her life.
Meanwhile, Go Eun-byul lives in Seoul, popular, sharp-tongued, and fiercely protective of her boundaries. During a school trip to Tongyeong, Eun-byul crosses paths with Eun-bi and realizes they share an identical appearance. Shortly after this discovery, Eun-byul mysteriously disappears.
Eun-bi is rescued from the water, survives, and wakes up with total amnesia. Mistaken for Eun-byul by Song Mi-kyung, Eun-byul's adoptive mother, Eun-bi accepts the identity and transfers to Sekang High School in Gangnam.
- The Exposure: The tension spikes when Kang So-young transfers to Sekang High School after her parents force her to move away from Tongyeong to escape accountability. So-young recognizes Eun-bi immediately and spends episodes trying to expose her true identity.
- The Return: Eun-byul isn't actually dead; she returns later in the series with her memories intact, operating in the shadows to protect her sister and dismantle So-young's bullying campaign permanently.
Main Cast and Character Breakdown
The series relies heavily on its young ensemble cast, who captured international attention through their nuanced portrayals of troubled youth.
- Lee Eun-bi and Go Eun-byul (played by Kim So-hyun): Playing dual roles requires distinct physical language. Eun-bi is soft-spoken, empathetic, and defensive, while Eun-byul projects cool confidence and sarcasm. Kim So-hyun switches between the two characters seamlessly, anchoring the emotional core of the show.
- Han Yi-an (played by Nam Joo-hyuk): Yi-an is a national-level swimmer and Eun-byul's childhood friend who has harbored romantic feelings for her for years. His struggle begins when "Eun-byul" acts differently after her accident, forcing him to confront his changing feelings.
- Gong Tae-kwang (played by Yook Sung-jae): The school rebel and class clown, Tae-kwang hides severe family neglect and an abusive father behind wild antics. He is the first person to realize Eun-bi isn't Eun-byul, and his unwavering loyalty to her made him a massive fan favorite.
- Kang So-young (played by Jo Soo-hyang): The primary antagonist. So-young represents the viciousness of peer pressure and unpunished psychological warfare, driving much of the mid-season conflict.
Production and Cultural Impact
Produced by FNC Entertainment and broadcast on KBS, Who Are You: School 2015 followed a long lineage of youth-centric dramas that started in 1999. While traditional Korean dramas of that era heavily prioritized straightforward romance, this installment leaned into darker social commentary. It addressed institutional corruption, parental pressure regarding university admissions, and the devastating psychological impact of cyberbullying and physical assault.
The soundtrack became an instant hit, particularly the track "Reset" by Tiger JK featuring Moon Ji-eun, which played during key dramatic turning points. The series also served as a major career springboard for its lead actors, earning multiple accolades at the KBS Drama Awards that year.
Common Misconceptions and Criticisms
Despite its massive popularity, the show drew sharp criticism from viewers for specific creative choices near the end of its run.
- The Romance Resolution: Many fans suffered from severe second-lead syndrome, heavily rooting for Gong Tae-kwang because of his emotional vulnerability and unconditional support for Eun-bi. The decision to stick to the traditional childhood-friend ship generated polarizing discussions across online forums.
- The Bullying Aftermath: Viewers frequently point out that Kang So-young's redemption arc or punishment felt rushed, arguing that systemic bullying requires more severe institutional consequences than what the script ultimately delivered.
