Qingya, a person with a beautiful face, pure and agile, is the daughter of the royal family of Qingguo, the weakest of the five countries of the "Tianlong Continent".

Qingguo, bordering Xiwu Country in the north, Beihu Country in the west, Nanque Country in the south, and Dongchu State in the east, such a geographical location may be the reason why such a beautiful and rich Qingguo cannot be strong after all-suppression.

But even so, Qingya, who lives in Qingguo, has never felt anything bad, perhaps because of her innate talent for martial arts, so that in this patriarchal royal family, she has won the favor of the king of Qingguo and become his favorite daughter.

Qingya always thought that she was happy, and she would be happy for a long time, but until she was ten years old, when her father took her into the royal family's secret room, everything changed......

She, the princess of Qingguo, is still the most favored princess of Qingguo, but every time in the dead of night, she has to sneak into the secret room of the royal family, and painstakingly study the "music scores" that are completely incomprehensible and cannot be understood by the ancestors of Qingguo.

Time passed slowly, and Qingya, who thought she would die in Qingguo, once again reversed the wheel of fate when she went to visit her aunt in Nanque Country with the royal family at the age of sixteen.

Back then, under the attraction of the piano, Qingya strayed into the willow forest, in the huge Nanque Palace, in the swaying willow, in the neat palace wall.

Qingya in the overflowing sword light, as if seeing a flying streamer, from a distance, like a pouring of milky ways, and like a fluttering firefly in the summer night, people are infinitely yearning.

Qingya, who was only sixteen years old, didn't know that when she stood under the willow tree, she was looking at the heroic yellow-clothed young man surrounded by the streamer with such admiring eyes.

That is the crown prince of the Nanque Kingdom, Que Chengyu, and the future king of the Nanque Kingdom.

Just this glance, Qingya fell, when the reality was a foregone conclusion, when she no longer looked forward to it, her heart was like water, how many times she recalled the first encounter back then, Qingya's heart was agitated, and she never regretted it.

Even when she learned that this was a game set up by her most trusted aunt for revenge, after taking the soul-snatching pills sent by the envoys of Qingguo again and again, at the last moment of her life, Qingya never regretted it, regretting the love at that glance......

Since entering the secret room of the Qingguo royal family at the age of ten, Qingya knew that the daughter of the Qingguo royal family married the women of the other four countries in order to steal useful information, and she had to eat poison every year as a sign of loyalty to the Qingguo.

Qing Ya disobeyed the order of the king of Qingguo, regardless of her mission, and had a plan when she left the Nanque Kingdom, with the help of her aunt's power in the Nanque Palace, she was willing to let go of the woman's reserve and the pride of the royal woman.

Under the same willow forest, with a girl's expectant and admiring heart, she played the song of this life's admiration.

Qingya always thought that that person would hear it, and even if she couldn't stay in Nanque Country as she wished, she would not regret that she hadn't tried to confess her heart to that person.

But the truth backfired, when Qingya heard the sound of footsteps, opened her eyes with excitement, looked at the pair of Ming Emperor's shoes on the ground and was surprised, and looked from bottom to top, she could never forget the pair of tiger eyes she saw at that time, the amazement under those eyes, and the sorrow in her heart.

Born in the royal family, raised in the palace, Qingya, who is not an ordinary person, understands the design of her trusted aunt in the blink of an eye.

It wasn't until later, when Qingya and her aunt faced each other that she knew that everything had been designed from the day she left the Qingguo Palace and first entered Nanque......
