Rindou was your senior in high school, so you knew that he was a gang executive.

12 years passed

You work in a big restaurant as a chef, and one night. One night you get the assignment to make food for a group of influential people in Japan.

You deliver food to a man who has a scar on his eye. "Enjoy your meal sir." You say to the man

"[Your name]."

Rindou calls you and when you look at him you recognize him as Rindou who has become a Bonten executive.
