Cerberus (Amuse Creative Studio)

Fukutome Kai (21), who lives with his mother in Shin-Ōkubo, Tokyo, is attacked by a stranger while walking his childhood friend Rika (21) home after his mother Sachie's (53) birthday party.

Kai and Rika manage to escape the scene for the time being, but days later, his best friend Park Yoo-jun (21), a Korean-Japanese, is killed by that same man. Not only Yoo-jun, but Sachie and Rika are also caught in the aftermath. Rika is left unconscious and in critical condition, and Sachie passes away.

Triggered by this tragedy, Kai uncovers several shocking truths:

• Yoo-jun was a spy for Country N.
• He has a long-lost twin brother, Lim Jin, a member of the hugely popular K-POP boy group Little Gang.
• His estranged father, Lim Do-hyeon (53), is living in South Korea.

Kai's fate begins to shift dramatically overnight. To avenge his mother and his best friend, and to discover his roots, he travels alone to Seoul.

What awaits him there...!?
