I Hear Your Voice (GMA)

The series is a combination of courtroom drama and romantic comedy with elements of fantasy. After overcoming poverty and a difficult childhood, Jang Hye-sung (Lee Bo-young) becomes a lawyer, specifically a public defender, but she is pragmatic, self-preserving and jaded. Her life changes when she encounters Park Soo-ha (Lee Jong-suk), a high school boy with the supernatural ability to read other people's thoughts by looking into their eyes, and cop-turned-lawyer Cha Gwan-woo (Yoon Sang-hyun) who is cheerful and idealistic, though a bit of a dork. 

Soo-ha gained his mind-reading ability after witnessing his father getting murdered ten years ago. His father's death had initially been dismissed as a car accident until Hye-sung, then a high school girl (Kim So-hyun), gave decisive testimony in court despite the killer's threats (Jung Woong-in), and Soo-ha has been searching for her ever since. As Hye-sung works with Soo-ha and Gwan-woo, she gradually lets go of her pursuit of money and glory. Together, this unlikely team use unconventional methods on their cases, proving that while sometimes justice is blind to a fault, she can still hear your voice.
