The God ordered me to do my last mission as an guardian angel

It was to protect this human. So I immediately flew down back to the Earth and searched for this human and hide my wings completely by making it invisible to humans eyes

I finally found the human but they're sitting alone in a bench in the park

A leaf flew by me so I took it and wrote something in it before letting the wind send my message to the human

"Bring this message to the human sitting on the bench" I whispered
