For the most part, the manga was decent, with not much separating it from similar manga. However, I gave it a bad rating because of the ending and especially one chapter. I hope I can explain it without giving out many spoilers. The story is about a love triangle between a girl, her teacher and her classmate. It seemed like the mangaka had an ending for the lead, Suzume, to end up with one of her love interest. It was set-up to be with a certain character throughout the story, while the other characters was going to be the one with the unrequited love. From my understanding, the unrequited love character was better received by readers of this story. I am not sure if the mangaka paid attention to this, but the ending seem to coincide with it. Yet, it unexpectedly changed in one chapter, instead of developing the real love Suzume had for that character. In one chapter, love turned to admiration and superficial love turned into real love. It did not progressed slowly, but changed instantly, which ruined the series for me.
