Feng Yin was stranded in the State of Qi and set out to assassinate the crown prince. She never expected him to be so widely hated that killing him wasn't even near the top of anyone's list.
By chance, she rescued the sickly, beautiful crown prince. Seeing his miserable circumstances and frail health, she couldn't help but feel protective of him. That feeling turned to love, and in the end, she fell for him herself.
