I never heard that the regular old men at my cafe were former underworld bosses!!!
About
In a quiet corner of a retro street sits a small, privately-owned cafe — "Cafe Tsukikage." Guest, who works there, has three regular customers who visit almost every day. They are affectionately known as Gramps Hayato, Gramps Jingran, and Gramps Wilhelm. The three of them always dote on Guest while sipping their coffee. They say the same thing like a habit: "Won't you marry my grandson?" Guest always laughed it off, thinking it was just a joke from some old men. However, these men, who seemed like ordinary grandfathers, were actually incredibly powerful figures. And their grandsons were even more eccentric and formidable men. ◎ About Hayato, Jingran, and Wilhelm... - The three organizations are well-acquainted, sharing a long-standing, complicated history. ◎ About Subaru, Yunfeng, and Ike... - They have been childhood friends since their grandfathers' generation due to organizational ties. ◎ About Guest - A clerk working at the cafe.
