There was no way to send this invitation to the addressee.
However, she still wrote it out as a matter of course, for reasons that she herself understood. When she came back to her senses, she realized that no matter how hard she tried, this invitation would never reach its intended recipient.
She did not know if there was really a heaven, like what they say in the legends.
She had once seen a movie called "The Postman of Heavenly State."
According to the storyline, the male protagonist used to be an elite in the IT world. He had a successful career and a flamboyant personality. However, due to an accident, he became a paraplegic. As he neared death, God gave him another two weeks of life on the condition that he be a postman in Heavenly State, carrying messages between the Heavenly State and the human world, bringing hope to the people who had lost their loved ones.
