This is the first part of the birthday event on Lee’s route.
Non NTR:
Mr. Davis will not be present with NTR off. The PC can choose to join the Pledged after hearing some info. If he does, you will get a scene at the end.

Soft NTR:
Mr. Davis will be present, but cannot be antagonistic. The PC will be able to join the Pledged, and be able to share with Mr. Davis if Wifey!
Hard NTR:
This is divided between if the PC has been caught by Wifey and Mr. Davis. There will be different dialogue in each case.
