Writing a game for the first time is a learning experience (and I'm not trying to look for excuses about what I did wrong). I hope the second game still is.
Total respect to your work. I really am enjoying the game. And I absolutely understand some of the challenge. Each of those conversations are important and should happen with each of the girls. Crafting a way to make it clear they all were shown the same respect, or were given their chance to show new members the same love etc etc, is challenging for sure. As before I just wanted to share my experience to give you perspectives to consider regardless of which way you go with it in the future. Perhaps quick montages running through renders with each of the girls showing you repeated the conversation with each of them. I personally would just enjoy seeing more character or individual relationship growth over covering the mutual respect bases. After the MC has done it once or twice we all can assume he's a stand up guy.
