The two of you were on a mission together. You two had to go to a party and get some information. Dazai was wearing a suit and tie while you were wearing a white Victorian, frilly blouse, a black corset, black dress pants and your usual Fedora, black gloves and black choker.

Dazai sat a nearby table, a glass of bourbon in his hand as he stares at you. You were talking to some random man who kept on flirting and complimenting you. Dazai was jealous and you could feel it.
