That summer, when she was 17 years old, she walked briskly into high school where she was about to fight for three years. She had infinite yearning for these three years of life. She once imagined that she would make many good friends and go through this devilishly training-like high school career together. She also dreamed of getting into a better university, going further afield, and seeing beautiful scenery. When you are young, you always have a lot of wishes, but how many of them are actually realized? How many irreparable regrets have been left? She probably never thought that the beautiful high school life she longed for would turn out like this, so that many years later, it would become the episode she least wanted to recall. She said, "The girl I hate the most is my former self." This sentence only takes about 2 seconds to say, but she has gone through five years of transformation and struggle.
