Emily had been bullied by Eliza and Beau before, so she wanted to take revenge.
It just so happened that Evelyn had come up with an idea for Emily. With their status and power alone, they were far from being able to compete with Beau.
If she wanted to get revenge on Eliza, she had to find a bigger backer.
Evelyn noticed that Emily's profile was somewhat similar to Roseane's. With a thought in her mind, she had an idea.
Before she introduced Emily to Gellert, she had specially put on a make-up similar to Roseane for Emily.
After all, as a famous actress and movie queen, Roseane's popularity was heaven-defying. The Internet was full of internet celebrities who wanted to look like her.
When Emily, who had been meticulously dressed, did not speak or laugh, she indeed looked a little like Roseane.
