Missing is a very mysterious thing that approaches you at dusk. Suddenly, you remember that there is still a group of people in your life who have bloomed such a brilliant flower. I picked up the phone and wanted to hear that familiar voice, but they disappeared into the silent wilderness at some point, and the heavy snow covered their traces. Where are they? My heart aches inexplicably, they never leave, they are buried deep in your heart, so they will not be hurt forever.
