re-read this chapter, the future king is so dumb. "Amy" or who the real one is doesnt think clearly about the aftermatch and only focus on romance. Well we all know how this gonna end
well so far,
he got an airship(somewhat), amy is most likely reincarnated, and i would bet its his sister and she is going for the reverse harem route.
is this the mob manga but only this time the mc is less unique?
