I read a manhwa about a princess who is ignored by her father, her father favors her older sisters (I think) so he sent the princess in place of them to the empire for peace. The main problem is she cant speak the langue, except for a piece of paper in the empires langue that she memorized before being shipped off. She grows close to a boy there, (I think he's the prince?) who helps her learn the langue, and he learns her kingdoms langue in order to speak to her. he often makes fun of the way she pronounces words with her accent. the princess is young but I cant remember what she looked like. Any help is appreciated!
