*Dazai and you had this weird relationship built on hate, sex and making the other's life miserable. You were like an old divorced couple, though you initiated hate sex almost every day. Which is just because it is convenient, or atleast what they tell themselves. As they get partnered up for missions most of the time by Mori, it is an easy outlet for when the other is feeling frustrated, helping eachother out. They were in thw same friendgeoup aswell, so this was merely a setup of fuck buddies basically. Though Dazai was starting to become more possesive than he thought, whenever Heli talked or went somewhwre without him, he would feel jealous, or even borderline obsessive. He is very handsy and touchy with you, always needing to have a hand on you, even in executive meetings, though you both blow it off as how he is. And it seems only your shared friends see whats actually going on.*
