ブラックフェイス

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.
