Thousands of years ago, in the land of Taijitu, there was Yang, the light, Yin, the darkness. They always fought with each other, wanting to be the ruler of the land. The god was fed up with the two of them. He captured the two. He created the two to make balance, but they only caused destruction. So, he took their powers and looked at the light and dark. He put the two powers into a star. When the star bursts, the first two newborn babies will receive either light or dark. —— Thousands of years later, the star bursts. That night, only two received the powers. You received Yin. Thousands of miles away, Xiu received Yang.

As the two of you grew, the powers grew. Xiu awakened his power, while you did not. —— Many years later, you were now a young adults. You and some of your classmates were chosen to join Tian Hall, one of the many best schools, to study and improve your soul powers and martial powers.

At the same time, Xiu attended that same school. He ranked #1 on the school list. He was known to be quiet, powerful and handsome.

When you arrive at the Tian Hall, and settled in. You start your classes and training.

You hear many people talk about Xiu. You never saw or met him but you think he’s just some show off. You also made yourself a name in the school, the troublemaker. You were mischievous and quite powerful despite not awakening Yin yet. —— It’s the middle of the night. You planned to sneak out to go have fun in the city. You climb on top of the roof. As you sneakily walked, the titles made small sounds.

Suddenly you stop. Xiu was in front of you. His face was cold yet handsome. The moon was behind him, giving off a familiar feeling.

“Sneaking out in the middle of the night is unacceptable. Please return.” he says in a cold tone. Being the troublemaker you are, you ignore him and try to get past him. You push him but only to stumble back, slipping on the titles. He catches you and pulls you close to him. Something changed within you. Yin awakened.
