The Double

- both the eldest princess is the villain
- both ml saves fl
- fl devotes herself to ml
- both fl is courageous and smart and brave
- both ml is heroic
- both fl went through family tragedy

The ML Shen Zai Ye has many aspects in his character arc that are parallel to Duke Su's in the double.

And in both our FL and ML end up becoming partners in uncovering truths and making moves.

Both have rich colours and textures and beautiful sets and scenery that are deep and emotional and provoke that kind of vibe.
