Overview: The man (Choi Fi-yeol) has no name. His codename is "008 (Gong Gong Pal)."
A cold-hearted Korean hitman is summoned to Japan for a job. While hiding his identity and working at Donhyun's (played by Yoshiyuki Yamaguchi) yakiniku restaurant, he saves a woman and ends up meeting Kaneda of the Hayamikai. “Let’s be chingu (friends).”
Kaneda, a regular at the restaurant, naturally works his way into 008’s life, forming a bond. However, Kaneda becomes a target of the invading Sakaki family and loses his life. For the first time, 008 has lost a chingu. A hitman who once had no emotions now begins to act on his own will.
Overview: Detective Kazami (Kazuyoshi Ozawa) is on the trail of his target, a mysterious woman. His investigation leads him to a secluded mansion where he witnesses more than just a drug deal—he stumbles upon a brutal murder. The killer? An Asian man who effortlessly eliminates multiple yakuza in a flash. As Kazami delves deeper, he uncovers whispers of this enigmatic figure in Okubo. Their paths cross unexpectedly, and tension rises as they come face to face. A single gunshot pierces the man's shoulder, throwing them into chaos. With Kazami's help, the two narrowly escape. Thus begins the peculiar cohabitation of "the man who saw too much" and "the man who was seen."
