Touch of the Frozen Heart

The fallen princess, Nangong Ying, personally stabbed Crown Prince Su Wuying, who loved her deeply, to avenge her kingdom's destruction. Su Wuying believed his heart had died the moment Nangong Ying poisoned him. Yet five years later, when he saw her living in harmony with the young general Pei Xian, that supposedly dead heart still ached and burned with jealousy, driving him to madness.
