I'm talking about this "Yeah she guessed the truth based on the story. As expected of the woman that i had chosen".
He told her everything! Only a total dumbas* wouldn't know he's talking about himself! Yet, he's impressed that she guessed it based on the whole package story she got from him ╮( ̄▽ ̄)╭

Aunt: How in heavens did she find out about your identity? O.o
The prince: She's smart, she guessed it
Me: facepalm. You LITERALLY tord her! She must have been deaf not to understand that!
