Oblivious NTR is something I would want. THe MC starts out acting as though he doesn't know what his wife is doing in the bathroom, but then suddenly she starts talking about him looking through the peephole (despite me never choosing to leave the tavern for fresh air. I would love it if the MC is genuinely oblivious to what she does to gather information, and genuinely believes her when she says that the Captain's visits are just her acting to keep him safe.
On a technical bug: on day four on Android I became unable to access the travel map, selecting travel just brought me to a picture of the wife without any dialogue with a button to cancel the travel.
