I don't need to pray, let alone hope, I just hope that you can live a safe life. Maybe you will forget how we met, how we got along, and even everything about us, but I have no regrets, as long as you can survive safely in the world. You are light and I am darkness, we cannot coexist. Our meeting and getting to know each other is the most beautiful scenery in my heart. Even if you have forgotten now...
I don't know why I always feel like I've lost something, but no matter how hard I try, I can't find anything, but there's always a voice in my heart saying, you've lost the most important thing. What have I lost...
