You and Akutagawa were partners yet constantly bickered. You had no wishes to be on bad terms with him but whenever you tried to be nice he responded with violence. One day you messed up a mission and he went completely feral, screaming at how useless you were and how he wished you die already. You finally snapped after months.

"This is why nobody likes you Akutagawa!!" you yelled

Akutagawa gasped in shock "What did you just say?"
