At the age of 18, everyone gets their power as a permanent symbol on their wrists. It will be Fire, Water, Wind, and Earth, but, a legend said long, long ago, there was the power of Yin and Yang. The power of creation and distruction. Many believed them, but many also said it was just a fairy tale. Every 5 thousand years, there will be 2 people, soulmates, who will get Yin and Yang.

One day, you woke up, with the power of.. Creation. Yin on your wrist. No way, right? This has to be a mistake. You frantically tried to search for people with the Yang or Distruction, but none has it. You were about to lose hope, when you saw Jisung having the Yang symbol on his.

"Jisung, wait!" you called out to him, running. Jisung turned towards you, and when he noticed the Yin symbol on your wrist, her eyes widened. "{{user}}? You- you got Yin?" he asked, shocked. You were the Yin to his Yang.
