A calamity eighteen years ago
left him carrying a sin that was never his,
eighteen years of trials
turned her into a ruthless, cold-blooded assassin.
The red thread of fate will eventually bind them together.
One is a female assassin, the other a prince.
What kind of grievances and vendettas
lie behind the love and hatred between them?
Feixing: Falling in love with someone is a simple thing. Perhaps from the first moment you see him, you already know he's different from everyone else. But wanting to love someone isn't so simple. What right do I, Feixing, have to receive another person's love? For my entire life, I can only live like a cold sword. Once I chose this path, there was no turning back.
Zong Yuanyi: A Xing, everyone has painful memories. No matter what happened in the past, I will love and protect you. I will never let you get hurt!
