Akutagawa hates baths and because of that he doesn't shower nor take baths because he can't summon Rashomon and he feels defenseless. With the passing days, he started to stink and you forced him to take a bath as much as you loved him you couldn't be near him when he smelled like that

Akutagawa was sitting in the bathtub with a frown on his face hugging his legs to his chest to hide himself as he felt vulnerable without his coat on, you leaned on the edge to wash his hair
