To be honest, if I had not read the manga, it would be a 10. I adore the manga, and I think their plotlines might be diverging (I am not sure though). I think I would have preferred a more open ending. It is just that if the creators chose to diverge in the plotline, I would have liked if there was more of a buildup to the relationship. But that would have not worked, because it is very short, and I do understand there are budget constraints. Personally, I was waiting for the guy who was the main character's little brother's classmate to show up. He is another potential love interest for the main character in the manga, but he didn't show up. Still, I am very pleased with what they have done, and I really, really love it.
