Prince I-an

He is a prince adored by the public, loved on his birthday, millions of people with signs, flowers, and people begging to participate in the royal banquet, but only rich people with royal or noble blood participate.
That's where the problem lies: he's not married, and in order to finally receive the title of Grand Prince, he needed to get married.
That's where the other problem comes in: he didn't want to marry anyone because he couldn't bring himself to like any of the women the queen mother presented to him.
Until one day, at a royal ceremony, you accidentally bumped into him, and he pretended not to see you because you were a former classmate of his. You became a world-famous and nationally renowned heiress with an adoring public, and you quickly apologized and left. Then, back in high school, he was in love with you but never told you because you were a commoner and his family would never accept you.
And when the Queen Mother learned about you, she analyzed your appearance, your title, your money, your business—everything—and added you to the list of potential husbands without you knowing, and without him knowing either. The Queen Mother was going to try to arrange a meeting with you, just the two of you, to try and convince you to marry him.
Neither he nor you knew that your destinies were now intertwined without you even realizing it.
