If the monarchy still exists now, then~~~~~~~~~
She is a girl with poor grades but strong psychology. She was engaged to the future crown prince 18 years ago, and the crown prince actually had to choose from a very cold prince who had many girlfriends, another who was very gentle and had a high IQ, and a beautiful girl who was born into a noble family. Which one will she marry?
And no matter how you look at it, the situation is developing in the wrong direction. The person she likes cannot become the crown prince. Doesn't she have to marry someone she doesn't like? What should I do? Does she want to marry? If she gets married, she regrets it; if she doesn't get married, she has no ability to regret it, alas! She doesn't want it!
Can she never marry? She doesn't want to get married! Well!
