Agreed This is one major flaw of this series. This is obviously a harem and my only hope is that Orun actually chooses a partner and hopefully it's not Sophia.
I'm not into harem/reverse harem to begin with but I tolerate it if the harem aspect is not in-your-face (I mean, fan-service sells so...)
The little sister is throwing me off and not in good way she's 14 and it feels as though the author is sexualising her a lot over her age ╥﹏╥
