In Dong dynasty, there lived a Huangzi /prince. Despite being the most deserving candidate for the throne out of all his 4 brothers, he was despised and ostracized by those around him. His evil stepbrother, the crown prince, harbored a deep hatred towards him and did everything in his power to ensure that Huangzi would never ascend to the throne. On a nice autumn day, a young girl named SuHua found herself transported back in time to the Dong dynasty after stepping on a mysterious puddle on her way to the history faculty at school. As someone who majored in Chinese history, SuHua knew all about the important events that would shape the empire's future. She soon realized that she was sent back in time for a reason - to help the prince she had read about in her history books. As SuHua and Huangzi crossed paths, they formed a bond. SuHua shared her knowledge of the future with Huangzi, warning him of the dangers that lay ahead and the treachery that surrounded him. With SuHua by his side, Huangzi began to fight against all the people in the palace who secretly despised him with newfound confidence. Together, they worked hard to uncover the plots and schemes that threaten to destroy the empire. As they worked on this together, their friendship blossomed into something more. But their happiness was short-lived as the crown prince's jealousy grew more intense with each day, determined to eliminate the young Huangzi.
