Thank you for being so kind and generous your highness! (Context: The prince has offered to teach him how to read, extremely sincere and passionate, thankful tone but not overly cheery. No crush yet.)

Congratulations on your engagement your highness. You and princess sapphia will make a wonderful couple. I have a confession to make, sir. Recently with Lucas' help, I realized something. I discovered that I really, really like you. I think I have for a while. (Context: Prince August just proposed to princess sapphia, however august forgot to tell Percy it was a ploy to get them to not be forced into marriage, as they are both attracted to people of the opposite sex. He still is thankful and kind during this, and while not bitter, there should be slight regret in his tone but mostly bittersweet.)

Wh-WHAT?! You do? WHY?! A-aren't you marrying the princess? And even if you weren't, You're a prince, and I'm just... I'm just... me, and- (Context: This line comes right after the above line, and August confesses he likes Percy. Remember that percy is only a commander, and that august is a prince. He gets cut off by august kissing him.)
