Was it necessary to strip the guy?
In the case he was holding hidden weapons, sure, it might have gone a little overboard for the sake of being 'thorough', but since it's been done to so many people after assaulting a princess in a previous chapter, I guess this just became the common method for the vigilante group when handling villains.
Follow your heart this time.
I don't know, man, in this case, I think the guy was following his dick. Wasn't even thinking how much of a 'history' she has with other patrons visiting the brothel and whether she was that 'affectionate' to them all for the sake of her job. And how long have they known each other 'in the brothel' for him to come to the decision of proposing to her? What about what she's like outside of it? Have they ever even gone out on a proper date?
If he looks past her relationship history, well, more power to him, but I wouldn't be surprised if he got turned down.
Also, while I sort of understand Else still sticking around in town as she tries to come to grips with the reality of the situation
and has apologized to Reda for her rude behavior towards him, it still seems like she has something to hide that couldn't be good. What was she holding back from telling him before he left?
