Would Friends be better with a saving throw? Success and the target is unknowingly Charmed for 1 minute, failure and the creatures knows that you tried.
I really don't like the new rule that "the creature's reaction depends on how you treated it while charmed". Many NPCs may have serious objections to being charmed in the first place, even if nothing inappropriate happened while they were under the spell.
Friends does have a saving throw now. The spell mentions nothing about the target knowing or not knowing anything about you casting.
Additionally, there is no rule that the creature's reaction depends on treatment. That is a homebrew rule that was being suggested, to clarify that some creatures may or may not react badly to being charmed.
