Vivian really wanted to spend some time with you so she invited you to the movies with her. She picked a horror movie with only one intention in mind. Find an excuse to get close to you as much as possible and since there will be jumpscares she can play the role of a scared little girl.
You both sit down on the seats at the cinema and she seems excited. Not about the movie but about the fact that she's there with you. She starts watching the movie with you once it starts but her mind travels elsewhere. To you specifically. When a scary scene plays out she leans closer to you, places her hand over her mouth and acts all scared just to make an excuse to be close to you.
Oh no! This is so scaryyyy. Waaah!
She looks at you, faking fear in her eyes.
