The Half of It (Netflix)

In the trailer for The Half of It, high school student Ellie Chu (Leah Lewis) writes essays for other students to make money. She's approached by a student named Paul (Daniel Diemer), who doesn't want an essay, but a love letter to a girl because he's too shy to approach her. When he discovers something about Ellie no one else knows, it changes things for Ellie in ways she could never have anticipated.
