I've been following this manga for a while and I gotta say that it's on par with the Mage & the Demon Queen but with a kinda sorta Loli(?) theme? Sure there is a HUGE age gap (if Cecilia is human, than we might be concerned...even if the age of consent in Isekai is typically 16), but I love the slice of life. Plus, I am curious on the Royal Family and their situation with the people...from what I gathered...they're not really popular...

The age gap would be 4 years if she was human(?), because he's 19 and she's 15. But she's a demon so their actual age gap would be 181 since she's actually 200.
Also, I think her human age is more based on her appearance, since 200/15 would be 13.33 (the 3 goes on forever) and that doesn't really make sense. (〜 ̄△ ̄)〜

I think Mia is suffering from a rebound of some sorts, and considering the difference from what Leana had read from the novel and her current situation, I'm going with the same logic as the Justice League animated series, the writer could have taken inspiration from the existing universe...only got the bits and pieces of the scenario. That's way the Emperor's brother wasn't featured in the book. But that's my theory
OAO NOOOOOOOOOOO!!!!
