When she was a child, she gave him a lot of trouble because she didn't have a photo with her mother; when she was in elementary school, no one knew that they were siblings, but a few people knew that she once had a sister; when she entered junior high school, she discovered her feelings and did something she could not take back; in high school, she decided to leave and left everything behind and fled to another city for three years, but she never expected that the two would meet again in college. There was no way to choose her fate. Even if it was short-lived, she still hoped for a moment that she could be brilliantly lost in the light like fireworks.
