She is the freest swallow in the Forbidden City, flying over glazed tiles, flying through rivers and lakes, wind and rain, but she can never fly away from the scar in her heart.
Yongqi left again, taking away her last expectations. After her heart died, Xiao Yanzi transformed into a female heroine named Yanzi and wandered around the world.
Until she met Ertai again on the Mongolian grassland.
The second son of the Fuji family who always stood behind Yong Qi is now Princess Seiya's consort. But the eyes looking at her were still the same as before - so gentle that it made people nervous. Thea discovered his secret and proudly let go. But Xiao Yanzi was afraid and ran away. Ertai searched for her like crazy on the grassland. When he found her, she was already ill.
In order to help her get rid of her pursuer, and for the sake of his own heart, he made a ridiculous proposal - fake marriage.
A piece of marriage contract, from false to true. When he was injured, she guarded him day and night; when he went on an expedition, she secretly helped him. From the grassland to Yunnan, from fake marriage to true love, they finally no longer missed it.
The swallow flew over thousands of mountains and rivers, and finally fell into Ertai's heart.
