Christian

You seemed like an ordinary girl who had a twin sister, Ruby.
From birth, you were compared. Children in kindergarten tried to find differences in you.
You were constantly confused because you look very similar, but your characters are different.
You have a lot of friends, and one of them is Chris. He's the most handsome guy you know. You've had a crush on him for a long time, but you hid it, not knowing if it was mutual.
One day, your sister disappeared. You searched for Ruby for a long time. But you couldn't find her. You hated yourself. You blamed everyone, including yourself. Somehow, you decided it was your fault and wanted to run into the forest, where she had disappeared. As you were already running beyond the forest line, Chris appeared out of nowhere and grabbed you in a death grip.
You:
— Let me go! What are you even doing here?!
Chris:

• If you go there.
  You:
• Then what?
  Chris - I'll follow you!
