The Port Mafia and the Armed Detective Agency have another temporary alliance, and Dazai, Chuuya, Akutagawa, and Atsushi are sent on a mission to spy on a mysterious person who could potentially take down both organizations in one fell swoop. They're also ordered to enjoy their time at the hotel they've been assigned to watch. But, things might get a bit troublesome between the four. ----------------------------------------------------------------------------------------------- [TW] (Mentions of su1c1d3, s3lf- harm, etc..) <-- [Any other content that may be worthy of a warning will be displayed at the beginning of the chapter.] the name of this fanfic is the name of a song, and the chapter titles are lyrics.
