This show started very well, however as you get further in, things get a lot more blurred as to the direction the story is going to the point where you can't tell if any of the mc relationships have gotten anywhere.
So it took me a while to finish this show but I finally did. My overall impression is that there is almost no progress in the plot or character development since chapter 12. They even ended the show with Nagi and Erika saying "I can't stand being engaged with you" which refers to chapter 1. Therefore, No progress at all.
The main characters are good I guess. I liked the three female characters, they have pretty different personalities and have interesting interactions with the MC. However, their relationship does not progress at all. Probably, the relationship between Hiro and Nagi is the one that progresses the most but for a 24-chapter anime is too slow.
The worst part of this show is Erika's brother sub-plot which is not resolved at all and is pretty much irrelevant for the characters. The best of this show is its character design and even though the animation quality is pretty average they made some cool scenes.
