Mc was a Japanese (maybe) or Vietnamese person. One day she was eating a riceball and a gem came out. The gem looks like a shiny orange colour, she was drawn by it and touched it. Next thing she knew she was a baby and the youngest princess of a country or nation.
Time skip to when shes 6, she gets use to her life relearning things and learning new things because she has the burden as a princess. As she woke up she was called by her father, she got dressed and went. Her father then said that shes engaged to another prince. She said no because she 'never' met him. (in actual fact she did), The father was troubled but eventually said "you can postpone (set it off) the engagement but in return you have to do a huge achievement that everyone will acknowledge you. She agreed and left.
Even more time skip, she is now working even harder to make a achievement that will be recognised by her father.
Soooo I'm confuse nd can someone explain like please I still don't get the story
