The two met in elementary school and became friends.
The companionship in junior high school inspired one of them to become a senior and school girl.
The care of the high school separated the two. One was focusing on the key points and the other was ordinary. They became a student of this school and a student of that school.
The meeting as adults made the two strangers. One lived in a big city and the other lived in a small county. They became the shining moon and the dim stars.
The gentle and considerate moon vs the sensitive and ordinary stars
