I read this manga twice, the 1st time I read it through, I just treated it as a romcom and it was pretty funny and very erotic. The downside was, I was oblivious to a lot of the foreshadowing until towards the end so the ending felt rushed to me and kept me from enjoying the series. A few years later, I decide to do a 2nd read through having forgotten most of the details. I knew the general outline of the ending though, and that clued me in on a lot of the background and made the ending very emotional. The author definitely plannedout the story well and made a series that seemed to be about fanservice very emotional.
