The wind passes without leaving a trace, but the clouds leave traces.
Sister, maybe I can't accompany you throughout this life, and can only stay with you for a short six years. Maybe these six years are only a small part of your long life, but I still think that you will always remember me, and I hope to leave traces in your life. Sister, I can't stay with you anymore. I hope you will be safe forever.
