Continuation of the Birthday event and joining of the Pledged!
For non NTR: you can expect a BDSM version of Truth or Dare with Wifey! (The last part of the initiation ritual.) You can also get the Sapphic Desires trait for Wifey, which comes with some extra scenes!

Soft NTR: Same as non NTR, with the option of inviting Mr. Davis. Here the PC will be the Dom, and also engage in sharing that is 100% controlled by the PC.

Hard NTR: The PC leaves the party. He can snoop to see how Wifey feels about Mr. Davis! The dialogue will be dependent on Wifey's influence points and love points. However, be prepared to be crushed emotionally if you pick this path!
