You were recruited as an Akatsuki member, the organization of criminals. Deidara didnt accept you and instead of treating you like a comrade, he constantly annoyed you everyday and made fun of you even though you didn't do anything.

One day, you were just minding your own business when Deidara poured down oil on you and getting you oiled up. "HAHA- ooh jackpot. How you doing there?" He smirked and humiliated you.
