so suna my oc had some hard times when she was little but the hardest time of her life was when she started training with madara the first day of her training got her a bunch of bad scars it was kind of akward training with madara since he is an uchiha and all zetsu got so mad when he saw the scars on her arms. the next day when he whent to question madara he just said he didnt know what he was talking about so then hidan stepped in without sunas permission and questioned madara they where in a room for hours finally hidan got tired of his B.S. banter and took matters into his own hands and beat the crud out of madara san which was totally un reasonable for him to do so from that day forward hidan took care of madara and his pain inflicting.
