I'm quite confused... why was this particular plot point rushed like this? I feel like it could have dragged on for another two volumes so that it could have developed completely. Not saying it was rushed in a bad way, or that it ended badly. I did see it coming that the brother being a criminal was the most likely come out, but I think there were lot of unused elements and it doesn't feel like it was out of the author's choice to have them underdeveloped. I mean, love rival Tachibana was barely there, Rize didn't get to grieve the loss of her brother's memories, it felt like things we could have seen played out through at least four chapters being condensed in the span of a single chapter. Again, I don't think this was because of the author not knowing how to pace the story, so it makes me wonder if it was rushed on purpose. Regardless it was actually really good lol, felt like watching a dorama.
