Passenger X was sitting in XXC.  His relative; Passenger Y; was sitting across the aisle at XXD.  They decided to upgrade themselves to better seats.  We told them that they were welcomed to upgrade; but they would have to pay the extra fee.  After much ado; they decided to move further back in the cabin.  Then Passenger X decides that he doesn't need to wear his mask.  We asked countless times for him to wear his mask.  Many announcements were made.  Every time; after we walked away; he took his mask off.  Once I awakened him; asking him to put his mask back on.  He said that he was eating.  I said; 'Sir; you were sleeping.'  He was putting all other passengers on board at risk.
Flight Attendant reported a passenger did not comply with face mask policy during flight.
