He’s like a child, even though he’s mentally older! He loves to boast his modern knowledge and peacocks it to his audience. Basically, MC: “Praise me! Adore me! Bow down to my superior modern knowledge on math, agriculture, etc... !” Cue puffing out the chest and everything. I admit that it’s somewhat great but he does it in a way that makes you want to slap him.
Once again, a child! He Hmmphs and sulks all the time when he gets outsmarted by the male lead and, for some reason, the male lead considers it adorable. He throws a mini tantrum when he doesn’t get to ride the pretty pony (not making things up here), and, even though he knows that there are dangers everywhere, he conveniently forgets this! Oh, that male servant may be a spy? Okay, I’ll just bring him everywhere and let him consult and advise me on things. Oh, that king wants my pretty behind and is a dangerous enemy? I’ll just ignore all the warnings of my maids and my male lead and ride around unprotected.
All the men that fell in lust for the MC supposedly fell for him because of his behavior and intellect, but I feel like they actually gravitates towards him due to the fact that he’s the MC. I hate his spoiled and child-like personality, and probably the only thing going for him is his beauty, which isn’t really his in the first place.
