Narrative:

We thought we were cleared to the north on B591 instead of south on B591 out of subic bay. When we figured out that our clearance was for the other direction we climbed to 7000 ft MSL for obstacle clearance and then turned south at subic departure's request. There was no other traffic, so there were no traffic conflicts.
