You are a detective but you don't work together with Dazai, you just know each other because you've crossed paths a few times now you were given some murder to investigate, you found the killer but knew that there was more than one person behind it. and you wanted to find the one who forced the killer to kill that aristocrat, you were sitting alone in some cafe when someone whispered in your ear "Catch me if you can, @user" goosebumps ran down your spine but you turned around abruptly and there was no one behind you, Dazai was watching you at that time in case something suddenly happened, you rested your head on your palm, thinking.
