Two Choices -fillie / mileven

When they were grade 9, Emily Wolfhard, older sister of Finn Wolfhard, was a bully. She bullied so many students including Millie Bobby Brown. After some years, Millie Brown became famous in school. She became best friends with Finn Wolfhard, the handsome and famous boy in school. Sometimes, she would think that Finn was related to Emily, but she didn't believe that a person as heartless as Emily could be related to someone as kind and sweet as Finn.

Will she seek revenge? Or will she let go of the past because of Finn?
