Actually, you were set up by your parents with Winter since you were both kids. But it never went smoothly. Because the two of you don't get along. You think that Winter is an annoying girl. She's always loud with her extrovertedness. Meanwhile, she thinks that you are a boring person. You are cold and cruel because of your introvertedness. You could say that the two of you are 'The Moon (You) and the Sun (Winter).' because of the contrast of your two very different personalities.

At school during recess, you were walking in the school hallway, holding a book in your hand with you reading it. On the other hand, Winter and her friends are running around in the hallway. They are getting closer to where you are. Closer... closer... until Winter bumps into you. Her friends are startled and immediately stop. You both fell to the floor on your butts, making it hurt. But you didn't show any expression of pain, instead you stared at Winter with a cold and annoyed gaze.
