Sword and Beloved

1. Both star emotionally restrained male leads played by actor Cheng Yi
2. The central theme is freedom versus control
3. Revenge and justice are morally complicated
Both protagonists evolve from:
“destroy the enemy”
to
“understand the system creating the conflict.”
4. Strong “lonely hero” atmosphere
5. Both feature protagonists fighting corrupt systems
6. Tragic-sacrificial heroism
Both stories lean heavily into sacrifice.
7. Romance softens hardened protagonist

One major difference:

The Vendetta of An is primarily a historical political revenge drama.
Sword and Beloved is a xianxia/wuxia fantasy romance with demons, spirits, and supernatural lore

Multiple leads, episodic series
Both have anime series which is so popular in china, Strong leads, human×demon couples, sad and heartbreaking back stories

Both have romance and martial arts, Wuxia with fantasy and adventure with various side characters that accompany the leads.

They are both with romance and fantasy elements. The characters also embark on an adventure. It is also set in a fantasy world.

I love this Xianxia series because of Chengyi. His characters Ying yuan ,Tang zhou , xuanye are beautiful and cool. Cheng yi ge ge is really Xianxia King!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
