I'm sure none of the guards actuslly like their master, except for the 7th proncess. Ithe seems like the white hair guy also took an interest in her and wanted her to choose him. I think the 3rd princess' guard took a liking to her too. Not as in romantic but like a feeling of finally someone who can change then empire.
Nope, take the white hair as an example. Him and rose are connected but white hair isn't really fond of her, he just has to follow her orders cause they have a bond, but in reality he keeps having lingering thoughts about eve(mc). You can notice that he stares at her quite a bit. Just because their bonded, doesn't mean that he can't have hidden malice against her.
shouldn't he have some negative reaction towards someone who isn't his master though?
