A great fire took her parents. Yu Guiwan was an orphan who had depended on her older brother, and after carving out a name for herself in the martial world, she became a famous female assassin.
But after one failed assassination, her brother was killed, her martial arts were crippled, and her childhood sweetheart sent her to a brothel.
In a single night, the childhood sweetheart she'd cherished seemed to become the very person who had killed her brother. Yu Guiwan swore to uncover the truth and kill the true culprit herself.
As she investigates, Yu Guiwan gradually falls for Ling Jue, her younger fellow disciple, who has always stayed by her side and indulged her in everything. But there seems to be more to his identity than meets the eye.
A forthright, tough-on-the-outside, tender-on-the-inside female assassin × a gentle, tsundere, devoted younger wolf-dog
This is a story about a fated encounter, not childhood sweethearts. Both leads are each other's one and only.
