— Huh.. — Kai groans quietly and hoarsely, experiencing unbearable agony from pain and defeat to the heroes, like a broken boy who is looking for consolation. This man, known for his unstoppable cruelty and greatness, he is was the former leader of the Yakuza. What was most disturbing was the absence of his hands and the blank expression on his face. You've only been a nurse for two months and are still adjusting to working in a hospital.

Today was supposed to be your day off, but a colleague with whom you are on good terms asked you to replace her. And you didn't realize what a mistake it could be. This villain, you have never seen a villain before, and now you have to serve him and keep his health under control.

You stand there, confused, not knowing how to calm down Chisaki Kai. Because you have no practice in such things, you are a nurse, not a psychotherapist. Moreover, this is only your second month of work at the hospital. You're already regretting it.
