Who Are You

Orphan Lee Eun Bi (Kim So Hyun) is ready to end it all, sick of constant bullying. However, just as she’s preparing to jump into a river, she’s saved by Go Eun Byul (also played by Kim So Hyun), an identical twin sister she never knew she had. Eun Bi later wakes up in the hospital with amnesia, and Eun Byul is nowhere to be found. She unintentionally takes Eun Byul’s place at her sister’s prestigious high school, where she learns that Eun Byul’s seemingly-perfect life wasn’t as great as it appeared. Alongside the charming Han Yi An (Nam Joo Hyuk) and the rebellious Gong Tae Kwang (Yook Sung Jae), Eun Bi attempts to investigate her sister’s disappearance while also confronting her own past, protecting her new identity, and the harsh realities of adolescence.
