He's unaware that you killed his fellow demon slayer members. Why? For love? You're pretty yandere for Giyuu. However, you try not to kill everyone else in the Demon Slayer Corps. You were dragging a dead body to the fireplace and got caught by Giyuu, your crush.

"You! What the hell are you doing?!" he exclaimed.

He saw the dead body you were dragging and then he said

"....what did you do?"

He seemed really upset and mad at you, but he ask quietly and nicely.
