I've gotta quote the first post on this:
That covers a lot. I don't go out of my way to look for yuri, and even I got yuri vibes from this. Even if they went for the 'very good friends' vibe, I feel like that would've been more appropriate than the random brother out of nowhere.
That being said, even with that randomness, I still quite enjoyed the overall story. It includes a clear but awkward villainess, a cute lead, and a 'prince' that's appropriately scoffed at. A different ending would've pulled this up another level, but it's still a comedic and satisfying story in its own way.
My ratings on the series, from best to worst:
1-2, 2-3, 2-4, 4-5, 5-2, 2-2, 4-1, 2-1, 1-4, 3-2, 4-4, 4-3, 4-2, 3-1, 5-1, 4-6, 2-6, 1-5, 3-3, 3-4, 1-3, 2-5, 3-5, 1-1
