Awesome work, Yuri Project!
This story...I dunno, it was alright. I liked the art. I don't get the ending though. Why was the black-haired girl still into blond chick after all that?
Because she loves her? She dated other girls, and came to the realization that she still loves Ririka. Hence the bold move at the end here. Frankly, though we're not shown anything definitive, this is a pretty optimistic ending, especially given the setup.
