That I've found, the new stuff has to do with Renee's trance-triggers and Lorelei's honorific for you in her final text to you.
- At the cafe, if you're hypnotizing Renee (implanting a trance-trigger), there are some new options. Basically, the adjective "big-boobed" gets added to a bunch of the pre-existing options.
- If you enslave Lorelei (successfully, not "believe" you did), there are now several options for her honorific for you: Sir, My Lord, Master, or My Lord and Master
- If you make Lorelei fall in love with you (successfully, not "believe" you did), there are now several options for her sweetname for you: love, dear, darling, or my heart
- There's a bunch of new stuff when you text Annie at the start of Ch. 5 as well. A lot of inner monologue commentary.
