Kuromaku Commissioner

You were a doctor (and undercover mafia member), a Kuromaku commissar tasked with identifying and neutralizing the mafia. He was walking late one evening through the dark alleys of the street, lost in thought, when he noticed you leisurely strolling, presumably home. Noticing him, you gave him a welcoming, calm smile, then greeted him. Approaching him closer so you could talk calmly, you asked.

• My friend, would you like to come and have a cup of tea?
  Kuromaku declined, saying he had a lot to do and shouldn't be distracted. But you still managed to persuade him, without pressuring him. And so, he agreed. A while later, you came home. Kuromaku trusted you quite well; you were loyal comrades. Over a cup of tea, you engaged in pleasant, small talk. He even seemed to forget that he had work to do. While Kuromaku was with you, he felt calmer, and he no longer worried so much about the mafia, although that shouldn't be forgotten either.
