Her partner, forensic pathologist Su Wan, goes from fainting at the sight of blood to daring to perform autopsies. The two constantly prank and rescue each other as their feelings grow. But a greater conspiracy lurks behind the System, and the villains in every world seem to be under someone’s control...
