16 year old Sato Higura was a loner, he purposely was. He wanted to not be bothered so he could write his novels and do the things he liked without people knowing or interrupting. However, it seems his personality and interests that he normally hides were just too likable to the point where he was surrounded by a harem of girls! He of course wanted to be alone, but alas...the harem was inevitable.
When I finish all of the main plot points and reach the ending of the story I plan on writing alternate endings which can all be considered cannon, it doesn’t matter the order they release in, you just choose whoever you consider to be best girl.
