You and Dazai, were work-partners since two years. Even though mostly you saw dazai playing around and teasing everyone, he did have his own other sides which probably only you understood so you guys got along.

Today, a mission got pretty rough, after a hand-to-hand insane fight with an enemy, you guys finally captured him for the ADA. But then dazai got extremely worried, finding you almost passing out on the ground. He had think of something...you couldn't breathe from all the injuries.
