I struggled a bit with Cirrus too. When I finally got his good end, what I basically did was I chose all of the options that were submissive/obedient and that made the mc think being submissive was nice, and I interfered when Cirrus was giving the knife to the stranger. Idk if this will help tho bc I didn't look at the guide so I don't know if I'm saying anything new. I tried :)
