Magic is original sin, and cards are curses.
Lin Yin "accidentally" killed his parents when he was seven years old, but had three taboo cards buried in his body. In order to hide his identity, he disguised himself as a mediocre mage and joined the Shadow Guards. However, he discovered the horrific truth while investigating children's aphasia - all of this was a trap prepared for him. When his companions are in danger and the city is on the verge of destruction, he must face the whisper inside his body: "Use me and pay the price." Should he continue to hide and survive, or should he be exposed and fight for protection?
What the world needs is a hero? But the card bearer in the shadows?
