It was 3 stars and I thought it was such a nice manga with a good plot, cute couple and healthy relationship. Wrong. The author decided to completely ruin their own work in a such a distasteful way. Really disappointed. Even though I quite like very toxic mangas this one was awful since it began so nicely. Why did the author ruin their own work? Just why???
Therefore in my head only the first volume exists.
