The love between two people is like a three-person world. There is no obstacle to who is who, and there is no third person who is who. They just met. Is it a coincidence or retribution?
He - the prince of the country! Since he was a child, he has been expected by everyone to strive to be a good son and a good minister, including becoming that person's future good husband; there can only be one word in his life: good!
She - the girl that everyone in the Prime Minister's Palace prayed for, was named after the country's symbol "Liu Li" when she was born. She was destined to be rich and bright and unchangeable, but she accidentally encountered that darkness.
"Hold your hand and grow old together with me" is such a simple promise, but it's not clear who that beloved person is. She has always loved only one person, why would there be two?
