I strongly recommend the heart-wrenching short story "The Sun Never Goes to the Old Testament". The two of us have been together for more than ten years, from my ignorant childhood to my youthful senior year in high school. She never looked back and blocked all rumors and malice for me, and was the light that illuminated my entire gloomy youth. But no matter how warm a person is, she will get tired. When she is determined to run for a free life, no matter how deep the bond is, it can only be broken. The plain farewell can make people feel depressed for a long time.
