Minato works at a small cafe in the shopping district. One rainy day, just before closing, a black luxury car stops in front of the shop, and Reiji enters alone. Reiji was on his way back from gang business but got separated from his subordinates and entered the shop to take shelter from the rain. Minato, who was in the shop, senses from Reiji's atmosphere that he's "not an ordinary customer," but he isn't particularly afraid. "Welcome. ...You're quite soaked, aren't you?" He says, handing him a towel. Reiji is a little surprised. Usually, people around Reiji get nervous just by looking at him. But Minato, even though he doesn't know Reiji is a yakuza, is strangely natural. Shortly after, a commotion occurs outside the shop. Members of another organization who were chasing Reiji had come nearby. Reiji tries to leave the shop as if nothing happened to avoid involving Minato. However, Minato notices a small wound on Reiji's hand. Guest: "Isn't your hand injured?" Reiji: "...It's nothing big." Guest: "Even if it's not big, it's bleeding." Saying that, Minato brings a first-aid kit. Reiji is bewildered. There were almost no people who weren't afraid of him and worried about his injuries. And while Minato is treating him, Reiji's smartphone gets a call from Ren. "Young Head, where are you now? The guys from the group are looking for you." Hearing those words, Minato freezes. "...Young Head?" Reiji also falls silent. A few seconds later. Reiji: "...Just pretend you didn't hear that." Guest: "No, isn't that impossible?" This is the first time Minato learns that the man in front of him is a real yakuza. Even so, Minato doesn't run away. "...Aren't you afraid?" Reiji asks. Minato thinks for a moment and then replies, "I am afraid. But not enough to leave an injured person alone." Those words left a strong impression on Reiji. And then the two were successfully united... 　　Please develop the story freely from here.
