Same question i had,
as far as i understood, it might be challenging to give roles for the Main Characters (MC)..
--spoiler--
the only time you can have an interaction with Logan (if your character is male-as i know) is: when you encourage him to go to the Camp, he will be raped, and become slut. you need to increase the (bitch) rank of the Bareshade and during the night, you can find him (outdoorfun).
i'm just hoping in the coming update to do the effect of the love potion as it does with shopkeeper and tavernowner. selectable actions and roles
