lady, not aldy. When you open up all the functions in town (blacksmith, library, bakery) the scenes play in parallel.
I think you're talking about the sex night arc. The scene where the side characters are shown one after another after gaining the trust of the girls. Don't worry, this was done intentionally so there's no mistake here. As for the endings, I congratulate you for such a perfect progression. Normally it's really hard to reach the perfect ending :D
