A pleasant trip, an embarrassing age, and a youth without regrets. Can they bloom their own light in a distant era? In the 21st century, Gu Xige and Han Yimi, who are inseparable, strayed into an unknown dynasty. One smile is like a blooming flower, and the other is like a still water. Who says women are inferior to men? Who says women can't hold up half the sky? As orphans, they have known for a long time that their backers depend on others. In the 21st century, they are geniuses in the eyes of others. They are proficient in music, chess, calligraphy and painting. They were both admitted to a famous medical university in the UK at the age of 14. However, a few people know that they have only worked a hundred times harder than their peers. No matter where they are, there is an everlasting principle - the fittest prevails! Even if they come to a strange and mysterious world, they can still be at ease, but there are many things that will never happen. After experiencing many changes, they continue to make choices and mature. As spring goes and autumn comes, time passes quietly between the fingers. Many years later, when they look back on the road they have traveled, will they shed tears or be devastated? Will Dongfang Zili, Lan Jinyi, and Bai Wenzi continue to ask themselves: "If time can flow, if fate can come back, if..." But there are no ifs in life, only results and consequences. . . . .
