Corner of Youth

I forgot who spent all my youth and time for me, and I also forgot who I spent all my youth and time for. Time has passed, and time has forgotten many precious things in the corners of youth and forgotten to take them away. However, the original appearance of youth should still be like this: There is no fixed theme, anything can happen; There is no established model, everyone is an artistic model; Joyful and unadulterated, more serious than sadness.
