Btw, methinks Diana will end up with the Prince, it fits.
mhm i don't see it. Iirc that's how it's originally supposed to go according to the game's story but so far neither of the two have shown romantic interest in the other (or any real interest for that matter) xD Diana has barely started not being hostile towards him
Could all be spun as romantic foreplay, the whole "you two get along so well" -> (in unison)"no we don't!"
Besides that part of the story isn't what natori is interested in changing
