I will say, it'd be nice if more of the options that gave love also gave trust, even if it were a small amount.
Since as of now, the only way to gain trust through every day dialogue, is to repeat your background specific (Art, Jock, Academic) compliment, aside from that the only other way is dialogue choices in one time events and things like studying and training, which isn't bad, and I get if the intent is to have trust harder to earn than love, but it can kind of grind things to a halt in terms of relationship progression when 90% of the most interesting character interactions like flirting don't actually reward you with any trust.
But also this is a much more minor complaint than what I may make it sound like here, it's just gonna take me a while to "grind" for all the trust I've lost since saves got reset.
