But there will be romance my dude ╥﹏╥ I don't know anything from the harem part but it seems, now if I remember correctly, drama with girls and him getting together with the elve princess. I don't like the romance part so I'll just read it and I'll stop when the love drama begins. Now I could remember wrong but that should summarize the love concept for the future.
Note that I got these spoilers from these topics, I haven't read the actual novel myself
I think there's no romance in this but still, he met a lot of girls since childhood and got close with. Well, he is amazing and cool that makes girls kyaa-kyaa but still! PLEASE DON'T MAKE THIS INTO HAREM.
