- Go to inn, talk to bartender select yellow option and pay 100 yuno or whatever the name is.
- Go through left door ( might need to tap multiple time on attack button because lag )
- Talk with people who have yellow option to drink (飲む option)
After that you will have 4 stages, one where you just arrived at bar, one where you drank one time, one where you drank 2 times and last where you drank more than 2. The standing-one leg-kiss pose is at third stage with thief on the right where you need to first let him touch you, then talk to him second time ( there will be a transition before he gets to that scene so don't be impatient ). You also need to get heart bar to full before doing that, kissing the prostiture is the easiest way.
For fat guy go through right door after third stage.
For "one night" event, get drunk until you will see multiple pink choice and only one white one, just select any pink.
