My gold standard for this kind of character-oriented yuri VN is definitely "Seabed" or the "Flowers" series by Innocent Gray. If you haven't read those, I'd pass on this one and just recommend those instead.

However, if you just want some yuri fluff with some relationship trouble and a character struggling with grief, it works pretty well. That's because "Highway Blossoms" is exactly that at its core. The story itself is ridiculous (who on earth would let treasure hunters vandalize public parks like that?), but that's no biggie. My expectations going in were not that high to begin with.

Whether you like this or not will depend on how you feel about Amber and Marina as characters. If you don't like them, you'll probably not find this very enjoyable. For me, though, Mariah was, by far, the best character here. I'd have liked to see more of her.

I did find this more enjoyable though than "A Tithe in Blood" if we're talking about other Studio Elan titles -- perhaps because it wasn't taking itself so seriously as that one and had more of an Americana theme. The music in this really is quite good and reminds me of my childhood growing up in South in the USA.
