Thank you, it's wonderful that our game has gotten you interested in the genre!
The "Danganronpa" series, "Black Closet", and "Long Live the Queen" are a few favorites of mine, but there's lots of variety in the genre. I love games with a strong narrative focus in general, and although these next ones may not be visual novels, I'd also recommend "Night in the Woods" and "Brothers: A Tale of Two Sons" as games with great stories.
