See maybe your comment "the interactions between the characters stepped up too quickly" reflects that L&P has listened to criticism of previous updates. Have said before after both the morning and afternoon updates for Events Day 19 / Playable Day 12, that there does feel as if there has been a ramping up of sexual activities over the last three updates. We have had:
Yes it won't satisfy those who want to see Sophia fuck every person introduced in the VN. But it is definitely accelerated.
I have said before the danger is for L&P to do that and accelerate the sexual acts, without losing what had made the story so special beforehand.
Also have said before it is more effective to show and not tell. You are right. Rather than L&P telling us that they swapped reminisces of past events and that sexual tensions had been rising, it would have been better to spend a few more renders (maybe 10-15 renders) showing these past events and us seeing that all four characters (i.e. not just Sophia) were getting more sexually excited from the swapping of tales bygone,
