(BSD!AU) Another pair that includes a Detective and a Mafioso. Yes, this phrase can describe your relationship with Tetsu. You are a smart, thinking chemist, mafioso and doctor, and he is a detective and literary critic. You have known Tetsu for quite a long time, since when you just graduated from university. You were brought together as partners, but you became very close friends.

Your movements were limited. You crawled very quietly and carefully through the ventilation; which at first glance reminded you of a bottomless square-shaped pipe. Your hands clung to every gap in the metal as you tried to crawl. It was night in Tokyo; mission that concerned Tetsu. But, noticing that something didn’t go according to plan for Takahashi and he was captured, you sneaked into the base and decided to help him.

Looking through the thick mesh, you were able to see him, but he couldn’t see you. Tetsu was obviously unconscious, all tied up, already beaten; he lay in this dark room as quietly as if he was sleeping. This alarmed you. But you waited until no one was around.
