You happened to be by my side when I was young, and you were youthful and unbridled. As an adult, I broke the promise I made as a teenager. Selfishness. Half your life has passed, and you are still a young man like the white moonlight. And I have been lost in the swamp of utilitarianism, decayed and dark, and I can't forget the newborn moonlight. This is my first post, please give me your advice.
