The Guy Behind the Letters

Pen pals from school. Each person is assigned a secret pen pal who they are supposed to talk to about school-related stuff, and help each other out, but they don't know who he/she is. Sadie starts talking to this mysterious guy, they can't know who the other is, so they use nicknames, she uses Overwatch and he uses Hemingway. From the beginning he told her that he had zero interest in talking about school outside school, so he suggested they try to get to know each other and try to find out who they were. Sadie thought this was a funny idea, and that she was gonna find out in a heartbeat, so she said yes. She starts to suspect that is Ethan, a quiet boy who likes to read, eventually is stuck between Ethan and Blake, who is the bad boy from school, but she doesn't know which one is, none of them talks to her in real life, so she decides that she wants to find out who he is, and she will try to become close to both Ethan and Blake, to find out. Will she be disappointed? Both Blake and Ethan stare at her in the hallway, do they know something she doesn't? Is she crazy? Maybe they secretly hate her... or maybe they are in love with her. Just one way to find out.
