Passerby-A is increasingly dissatisfied with their small part in the drama. By chance, Luo Ran was born because of this one sentiment. Her purpose is only one – to add scenes!

If you want to add scenes, you have to be with people who have more scenes. And those who have the most, are the male lead!

In the imperial harem, she is the second-class maid-in-waiting who died early beside the female lead.

In the immortal world, she is a flower demon who was mistakenly killed by the female lead before she was transformed.

In the CEO world, she is the smart secretary of the President.

In the entertainment world, she is a singer who has nothing to do with the male lead.

Luo ran uses these identities to attack the male lead and fulfill the desires of passers-by A; to add more scenes!

TN:

Passerby-A = Anonymous person, someone unimportant with a tiny role.
Add scene = to add value to a role with more scenes.
