This manga I thought got a bit messy towards the end, but overall was put together quite well. When it comes to the plot, there were a few plot threads, though they acted more like layers building upon each other, each with their own points focused on character development in the two main characters. The first layer is with Kyouichi living a tremendously boring life but managing to escape it thanks to Ashita, wherein she's ultimately his desires come to life. He is full of regret and wants to go back to how things were, which Ashita helps him do in a sense. However, upon this occurring, he realizes that that isn't really completely possible, that you can't just reject reality and live in imagination, but he overcomes that as well, and takes the feelings that were invigorated from being exposed to what he wanted and uses his imagination to push forward to a better reality. The point being, don't do nothing simply being regretful, nor attempt to go back to what once was, but do what's necessary for a better future. The second layer is regarding Ryuusei, or the real Ashita, and the other Ashita being something she summoned in order to help her achieve her desires. She too had regrets, and though she wanted to resolve them in the future rather than looking to the past she wasn't able to because of her stubborn personality and being afraid of things going wrong, but in the end Ashita does what she was intended to and helps push her along. The point being, it's better to go for what you want rather than regretting not being able to, and also don't be a tsundere. The way all of this is told can get quite confusing at times with it all feeling quite convoluted and the writing being prone to awkward info dumping, but ultimately I think it makes sense and the author's goals were achieved, and it ends the best way it could in a way that really goes out of it's way to make you feel happy even though there's some bittersweet aspects, which I greatly appreciated, though I felt that there was a missed opportunity and that if it had gone just a little bit further it could have been perfect. Along side this plot, especially during the first half, there's a lot of amusing situations that had great comedy as well as a loveable cast in terms of the main character and side characters who don't really get any development and are quite flat but work well enough in context. The art was pretty good.
