Unexpected? Such a bold statement is very much debateable

 

[rexmundi]

It is nice to have safe zone in each dungeon floor

 

[MiguelH224]

Of course, she needs a way to have sex with him more often, easier way to do that is to form a party with him

 

[Seraphus]

The correct response here, if any of you lads (or ladies) should find yourself in this situation is to look very troubled, and say that you really, really want to form a party with her, and then ask to borrow a room, and gently explain how you may need to use sage time in a few different ways, and this therefore requires frequent, non-excluisve dicking down of prostitutes and random adventurers.

It's the crucial first step to your harem!
Or, if they are also non-exclusive, it's just polyamoury...
(Unless they're an adventurer; then it's poly-armoury...)
