This one's a tough one... While it does tell a good story it did feel very rushed and all over the place at times. The ending was the highlight (that is, the last 4-5 chapters) and the story really stumbled over itself to reach it. A few chapters would really help it imo. The whole engagement with Tokiwo came out of nowhere while the two MCs we're still reconciling so the story had to rush their relationship and it felt really forced. I'd compare the premise to Kimi wa Midara na Boku no Joou, it's basically the same, but for some reason the mangaka decided tocompletely sideline that plot for a new one. At least they stuck by it to the end and managed to conclude it properly.

I want to give this a higher rating but I just felt confused for the better half, stuff happened so fast and I had to reread some chapters to catch up. I didn't even know the old lady was Kyuuta's grandmother until they said it... All in all I give it a 5 leaning towards 6 for the satisfying ending.
