not really, soo and sun don't know about the family stuff, and the family doesn't know about her, they might know about Tanja because of Lucy but I doubt it because Sandra would have talked to the MC about that, also Becca would for sure have talked about Fiona, the only family that knows about her is Mary, and Becca doesn't even know about Marry and Fiona much less the MC, These could all be done in less then five minutes of conversation with grouping, also repetitiveness is what we have the most in this game, look at "super naked ginger cuddle time", or the jokes, if we are going to repeat that we can as well repeat a conversation maybe 3 times at most that would demonstrate respect and communication in a poly relationship where communication is extra important.
Since I'm here I'll request some more things, like the MC having the choice to actually have a healthy polyamorous relationship and be able to actually tell the girls they are free to be with whomever they want, I want only maybe a 1 minutes conversation, with one render as background, maybe less, just the black of him having his eyes closed and talking to the girls, they don't have to do anything with anyone else, it doesn't even need to be mentioned, but it would be nice.
edit: Two conversations, this would work in two conversations, as Tanja already knows about him kissing Lucy, just in one of the familie's breakfeast say, I'm seing these people, and when meating soo and sun telling them.
