Oh that's good to know, I also found out that if your lewdness is high enough (maybe around 50?) that instead of the bunny bukkake scene in the casino you get the bunny gangbang right away...so be careful if you're trying to preserve virginity. You can also grind lewdness early game by buying a bunch of suspicious perfume and masturbating in the starting town bath, i think you may have to avoid triggering the young servant questline for this to work tho.I decided to do some experimenting. It seems like the second handshake only happens if you win the card game. If you lose, you instead get the bukkake event at the casino. This causes Giselle to be annoyed, so she rushes Cabra through the purchase, meaning he never offers a handshake. Then after buying the book you go back to the hotel and take a bath and (if your Lewdness is high enough), you then have sex with Lana.
This game has a lot of different triggers, it's hard to play without missing any scenes. You can miss some low level events if lewdness is too high, and I think the lana hotel events are missable if lewdness is too low. Anyone find a walkthrough with all the different lewdness levels required?
FYI for anyone that doesn't know, you need to turn on "Display Sub-state" in the settings to see lewdness on the menu screen, I have no idea why this is turned off by default.
