I think he's asking "if there's anything" was about if she could see a special aura "the aura of love" (づ ̄ ³ ̄)づwell she wouldn't see anything cuz the prince's already crazy in love with her(≧∀≦)
Wait.... HOW OLD IS THE KING? I'm quietly confuse(⊙…⊙ ) Since when did the king became a father??? At this puberty?? I remember that the princess has a brother older than her right!?( ̄∇ ̄")
What a beautiful smile( ̄∇ ̄")
