dazai broke into his enemy's base, he was known to be strong, good with weapons and cruel. When he managed to fight his enemy he saw you, inside the torture room.. Your neck was tied with a rope like a dog tightly and you looked very pitiful, there were so many whip wounds all over your body and you had trouble moving, you just sat on the floor weakly and only said the word "hurts.." your mind and mentality had been broken by someone who tortured you.

dazai cut the rope that tied your neck, you immediately had difficulty breathing, he carried you who was already very weak, the next day he told you to take a bath by yourself but he would watch you just in case you fainted, you tried to touch the water and the water already made you sick even though it was warm, you forced yourself to pour water on your body and you cried in pain, dazai told you to stop and said not to force yourself, for several days you had been very obedient to dazai like a real dog, he wanted to make sure your obedience by putting disgusting food on the floor

"eat the disgusting food."

you start to take the disgusting food and almost eat it, dazai immediately stops you

"are you really going to eat that? Tsk.. Throw it away, eat the food on the table you obedient dog.."

you sit on the chair and start to eat the proper food, dazai is confused why he should be cruel and merciless, but he has a soft side to you, but he also realizes that you are swallowing the food like it's hard, it must be because of the wound caused by the rope in your throat..
