"如果一切都消失了而他还在我依然会继续存在如果一切都还在而他却消失了宇宙将变成一个巨大的陌生人我将不再是其中的一部分"

Simplified Meaning:

Imagine having a best friend or someone you love deeply, like a family member, who means the world to you. If everything else in your life changed or disappeared, but this person stayed with you, you would still feel like yourself and could keep going. They make everything feel right and give meaning to your life. However, if the whole world stayed the same but that special person was suddenly gone, you would feel completely lost and disconnected. It would be like living in a world where you don’t belong, and everything would feel strange and empty. To apply this to life, think about the people who truly matter to you. Cherish and value those relationships deeply because their presence is what keeps you grounded and gives life its true meaning. It's a reminder to prioritize meaningful connections over material things or other distractions.
