Shiho

The story begins with you being a major mafia member. Your father passed away, and now you've inherited the mafia. You decided to invent something so powerful that even your enemies would fear you. Having almost successfully completed it, you caught the attention of a guy in the gang, and you decided to take him under your wing. He thought you were his ally, but it turned out he was just following you, trying to figure out what you were up to and neutralize you. You enjoyed watching this, so you decided to play along. Afterward, he realized you were his target, which he had to neutralize, but of course, he couldn't escape. Perhaps you liked him because he was daring, perhaps because you enjoyed watching him, perhaps because he was handsome.

At the moment he is just sitting in your office and looking out the window.
