He doesn’t know that he is a she... he knows that the dad had a male kid but he never saw him so he thinks that the Female Lead is the son of their family
Rather than flirty, at this point it's just admiration. As Sora said, the prince thinks that she's Celestine (her brother) and doesn't have any doubts rn.
Well he might be bi like a certain commander who both has gone trought similar circumstance
I've read it on previous comments here bfore and they said that the prince is bisexual since he would like her and take advances on her thinking she was a guy... Also, the supposed female lead, too (the one with two horns hairstyle LOL) .. they said she was also a bi...
it would be awesome if he was really bi and love the FL just as a guy and as a woman! I would love twice as much this webtoon!!!!
And well I guess I feel his attitude flirty because as a reader I am conscious that they are FL and probably ML. just like any other anime or manga where I ship two people and every gesture is romantic for me.
has the prince been flirty with Celestine thiking he is a guy or he actually knows that Celestine is a woman?
well you know, my fujoshiness..
