This VN is the only one IMO that comes even close to Acting Lessons in terms of multiple attractive,
interesting female characters to choose from. The "romantic" path cuts off a lot of content... you sometimes need to be kind of a dick at times to get some of the good scenes, but there several enjoyable paths if you want to be romantic and (mostly) faithful to the girl(s) you prefer.

This is a brother-sister story originally, but if incest isn't your thing the "standard" release is non-incest; you have to apply the patch to make them related. But it's sweet and romantic and quirky, but more day-to-day grinding than a VN.

If you like the slow build with Megan while enjoying other side-options along the way, you might enjoy Melody.

This game is only in its first release, but worth checking out!
Also, skim the pages in this thread and note which games people link or promote in their signatures. That's always an effective way to find games with similar tastes as yours.
But as you say,
So good luck!
