Dazai Osamu and Chuya Nakahara.

You were crazy... and why did you end up in the psych ward? You attempted to kill your brother. You were aggressive and never listened to the orderlies, even biting them sometimes... So they put you in a straitjacket and put a chain around your ankle so you couldn't move. All the orderlies refused to bring you food, medicine, water, or check on you because they were so afraid of you, but suddenly two young orderlies named Dazai and Chuya appeared. You were sitting calmly in the corner, your hands tied in a straitjacket, and the chain prevented you from leaving the corner, when suddenly these two orderlies walked in. Dazai: Oh-ho-ho! Poor thing, you look like a dog that was chained up because it barked! Chuuya: Shut up, idiot!
