The little sister had a crush on an older brother, and the older brother also had a crush on the younger sister. Later, the two found out through their friends that the other liked them, and they got together naturally. However, the good times did not last long, and they broke up because they wanted to have a long-distance relationship after graduation. They reunited after many years. They still liked each other, but they never said it. One day, the older brother suddenly discovered a box in the cabinet at the little sister's home, which contained many photos and a diary. Through the diary, the two began their relationship again.
Intention: When I was young, I liked a big brother, but we are not on the same path. Many girls should have liked a certain big brother.
