My name is Matsuda Yuan, a mediocre detective, with an extremely unreliable and violent brother, and a father who competes outside all year round and rarely appears randomly. Although I have a very unreliable family, my three views are still very upright. I am determined to catch all the criminals in the world. Recently, I have been very distressed and found out a little secret: my brother's young tame Ran who grew up with me and my brother seems to have a crush on me, which is really embarrassing.
Purpose: Set out for justice in the world
