They are superficial and submissive, and secretly set up traps for each other. Whoever reveals the secret first will die; but every time she rewrites her fate, her memory disappears. She must rush to uncover the old case of her grandfather who was chronically poisoned before she forgets it. She must also seek justice for the poison in her previous life and for his death for her in his previous life, and protect the man who seems to still remember her.
