If I were lariet I would've gone "I'm so sorry your highness, I promise to keep the secret the your highness is FLAT CHESTED to the grave. But its to early for me to go to my grave! So please don't kill me! I won't ever speak a word the your highness has a FLAT CHEST. Besides this is only for now you are still a child your highness just give it a few years it it'll grow bigger than these dumplings!"
And after that i will give him a present: a bra with boobs filled for flat chested people who want to hve a bit more. And we all will live happily ever after... wait im going crazy (▰˘◡˘▰)
