Xie Zhitang is a begonia struggling to survive in the quagmire, with the mark of "an orphan girl in the enemy camp" branded on her body.
Su Qingyan is the bright and cold moon above the clouds, her brilliance pours into the world, and she is a perfect gentleman admired by the world.
A political marriage bound two people who were separated by cloud and mud.
He came on the orders of his family, he was gentle and elegant, but he strictly followed the etiquette, as if he was a carefully planned performance.
She was soberly immersed in his gentleness, but she keenly captured the painful struggle under his perfect mask.
No one knows that she is the only "pen pal" who can see into his true soul, and the only "sharp blade" that can pierce his heart.
When conspiracies and betrayals ensued, she chose to push him away in the most decisive way, throwing herself into the situation and sacrificing herself, just to give him a way out.
Until that day, he gave up all his future and hugged her tightly in her wedding dress with burn marks.
Only then did he realize that this seemingly weak Begonia had already loved him in her own way for many years.
The bright moon shines brightly, only illuminating the begonia that was born for him.
