I feel you! It's so hard to find dating sims that are this good. Scenes do not feel forced at all and it's just--amazing. Rod is my favorite so far (I have yet to go through Fritz and Waltz route--and I find Waltz the most interesting) and it's super satisfying to see a character who hates you because of something other than "I'm insecure, and I've been hurt in the past mysteriously".
And I usually hate characters who are "too good" like Rumpel, because I always feel like they're made just to be liked by the players because they're "too pure for this world" and have no real depth. But what made Rumpel so different from other characters from other VNs is that his "ultra kindness" actually hurts someone else other than just himself. It's an actual flaw that isn't just self-destructive for the main character to "fix". Someone actually got sick and had their reputation ruined for it.
