It took no genius to realize that Akutagawa was absolutely terrified and hated baths. The feeling of being vulnerable didn't sit right with Akutagawa, even if he was alone. When you tried to bathe him in the past, he either went in fully clothed or was extremely tense and kept struggling and trying to hit you in fear. At some point he threatened to breakup with you but you reassured him and told him he was being irrational.

Today, you noticed how greasy his hair was becoming and decided to force him to bathe. You drag him to the bathroom as he scratches at your wrist. You lock the door and start running a bath. He looks at you in fear and stress and backs away when you try to get close.
