Watch: Ji Sung, Seo Ji Hye, And More Search For "Adamas" In Intriguing Teaser For New Drama

tvN is gearing up for the premiere of “Adamas”!

“Adamas” depicts the story of twin brothers uncovering the truth from an incident 22 years ago. The two will work as one in order to clear the murder charges of their biological father who was accused of killing their stepfather and to find the ‘adamas’ that is the evidence for the murder.

Ji Sung will be playing both twins named Ha Woo Shin and Song Soo Hyun. Ha Woo Shin is a best-selling mystery novel author, while Song Soo Hyun is a special forces prosecutor who works at the Central District Prosecutor’s office. Although the two brothers look alike, their personalities and approaches to tackling problems are completely different.

The teaser begins with Song Soo Hyun in a messy room, and his hands and face are covered in blood. He says, “The bloody diamond arrow.” Eun Hye Soo (Seo Ji Hye), the daughter-in-law of Haesong Group who has mysterious and elegant beauty as well as dignified charisma, looks intrigued as she asks, “Adamas?”

Kim Seo Hee (Lee Soo Kyung), a social affairs reporter at TNC, strides forward in a determined fashion as she claims, “I’m sure it’s the Adamas.” Choi Tae Sung (Heo Sung Tae), who is the general security manager for Haesongwon, asks someone, “Are you sure?”

More people call for the Adamas with greedy eyes, making viewers wonder why everyone is so eager to obtain it. Towards the end of the clip, Ha Woo Shin declares, “I’m going to steal the Adamas.”
