the first prince and the second prince are reincarnations and the hero's and ML of her novels ┑( ̄Д  ̄)┍, and she made prince kyte the villan both times, remember she is the author
her 2 novels was about 2 prince's, both of them were reborn, they now are heading to the second prince castle for the ceremony of the flower knight with the stupid psicho mitleloren princess, because they "want" vasser to come back to her world and make prince kyte the emperor, for that she remember there was a path from were the reincarnation of the second prince came from, the problem is to access because the second prince build a castle (if i remember correctly), so they are taking advantage of these to let vasser return to earth
so the second prince came from earth to and he will surely recognice those words, now he will most lickly take vasser, to help him get the throne and get rid of kyte because he seems to hate him (these is just a theory)ლ(´ڡ`ლ)
i totally understand you, i think the problem with this story is that, the important information is leaked little by little and they bomb us with to many blurry drawings of the fight's and to much filling (even though i am enjoying how the author is showing the love growing of vasser and kyte ε=ε=(ノ≧∇≦)ノ )
but i wish i would know what the monster want with vasser
also the characters don't have a proper introduction so it is hard to remember the names, because they don't mention them to much
with all these i still like the story(▰˘◡˘▰)
So, why was the prince so interested in what she said? How would he know what an Iced Americano and a cafe is? Hmmm.
