This manga has a premise that I think could work quite well. At a high level it's pretty much Tora Dora, but with very different characters in the roles. However, it doesn't do all that well on capitalizing on that at all. The biggest issue is that it doesn't develop relationships all that well. Suou and Hime have a good premise to develop a relationship. However, most of the relationship development between them feels superficial and one sided on Hime's end. The relationship between Suou and Kizaki is developed even less. Rather, we get very little development of her at all beyond some hints to her family, past, and such. Hence, while it is reasonable for Suou to be in love with her from the beginning, that still does nothing to develop any investment in said relationship with the reader. Hence, as the manga wrapped up, there wasn't really any ending that I think would really work in being satisfying, and as expected the ending is a major disappointment. On top of that, the side characters were really unlikable, the comedy beyond a couple good moments was pretty off, and the art was just okay. 

tl; dr: A manga with a somewhat interesting love triangle that doesn't properly develop any of its sides.
