You can find all of my yuri VNs on Itchio here!
If you only want free VNs, then Winter Fragments and Shut-in Vampire are probably good picks. They're both free yuri VNs which are very cute and light-hearted without much drama.
If you're alright with commercial stories, The Fairy's Song or My Dear Prince would be good (The Fairy's Song is one of my fav yuri VNs I've written so I'm a bit biased towards it haha)
