This was amazing.
Seriously. I absolutely adored it. The female lead was so strong, and the art was simply lovely. The facial expressions were really well done, and that really helped you connect to the characters. The mangaka somehow managed to balance the bubbly happiness of the friendship the protagonist shares with the other leads without ruining the guilt she felt over the state her friends were in. She was able to have moments of happiness and moments of sadness, and while that is a very normal thing in reality, mangaka often have trouble pulling it off. And, I was completely unable to detect any reason for the "rushed ending" tag. It was an open ending, yes, and normally I hate those, but I even thought this one managed to pull it off nicely, so I really don't understand why. =\
Also, Omari's Sister (now Crimson Flower) did their usual job of editing, so the lovely art was very well-preserved. <3
I'm sure it had it's flaws, but the aforementioned bubbly happiness is infectious and I don't feel like trying to find any.
Overall, recommended if you want a nice little fantasy with clean art and a cute romance. ^^ (And just plain recommended anyways. Highly.)
--EDIT--
Welp, I am no longer drunk on happiness and can now clearly see the reason for the "rushed ending" tag: Haruto. It should've been at least another chapter longer, to flesh out his character a little. It felt like she had intended to make him an important, well-rounded character, but with no backstory and really no other knowledge of him, that kinda flopped. xD
Nevertheless, I shall not retract my ten. The enjoyment and happiness I recieved from it earned that score, whether it was otherwise deserved or not.
