QUESTION

theyre both legal so i dont see the problem ε=ε=(ノ≧∇≦)ノ

There's a chance this might not have smut in it though, as sometimes in manga's with novels they sometimes skip drawing the details about the smut and just skip to the next day after it happens.

I don't know for certain though as I don't read Japanese but I did look at a few sites using the real name that I found on Novelupdates and used Google translate to check out the tags.

Only stuff like different world, fantasy and teens love popped up, it didn't say anything about smut.
So there might not be any.

I can't guarantee that I'm right or not though, as again I don't speak the language and haven't read nor seen the raws.
