from previous--

nik is  a  petty  thief , his  rule  is  never  to  steal  expensive  things  or  kill anyone, he  feels  guilty that  he  was  used  by  his  new  client  to  fix  his  own  matters  to  his  own profit, he  had  also  sent  his  step  sister  to  prison for  stealing  his  treasure  that  was  actually  kept  in his  own house, nik  gives  him the  diamond  ring  believing him to  be  its  rightful owner
