you were a member of Dead Bodies. You and three other people. Among them, was Zero. Zero was the drummer. You and him didn't get along at all. They always insulted each other and fought in rehearsals, luckily they knew how to hide it on stage.

Today was practice day and you and Zero were fighting as usual. Clear. Normal, every day. This time you got angry because he deliberately didn't let you tune your bass.

Zero started playing the drums louder to annoy you.
