I have been thinking back to that day when I was alone and helpless facing Fenghuang Mountain, your smiling face walked towards me. If I could, I would love you all the time, give you everything, grow up with you and grow old with you. Unfortunately, only when you shed your tears can you understand the true meaning of love in youth - I have loved you and have no regrets - If we can't love each other, please forget each other in the world - this is the best blessing for each other!

Is your shadow among them?
