Charlie and the planet G44

Once upon a time there were a couple of boyfriends named Charlie and Maria, they always did everything together, went out together, played together and always did most activities together. Once they were exercising, they were trotting along a very lonely road where it was not very usual to see cars, but unfortunately that day when they were finishing their exercise routine, a black car without registration passed with speeding and ran over Maria casuandole the death.

Charlie those days after the death of Maria, was very sad and went into depression, he thought only of her. One night, sitting at the bar of a bar, a strange character approached him. He was wearing a long black coat, inside which he hid his hands and unexpectedly approached Charlie, to realize the situation, Charlie felt afraid and wanted to withdraw from the bar but it was too late because the man in the black coat put on his shoulder a metallic hand, elegant and very heavy robotic to which Charlie could not do anything.
This man told Charlie that he had nothing to fear because he was friends with his girlfriend, that he had nothing to worry about that she was fine.
Charlie did not understand very well what was happening since he himself had been with his girlfriend in the hospital when the doctors told her she had died.
That strange man began to explain to Charlie that Maria was not an ordinary human being, that she was from another planet called G44, since her mother was an inhabitant of that planet but that her father was from the earth, so she I found on our planet. He also explained to Charlie that the inhabitants of the planet G44 always have two opportunities to live, for which Maria was at this moment alive on the planet G44 but could not return to earth anymore.
That man told Charlie that he was an android sent by Maria to bring the message and give him a super advanced electronic device in technology compared to the technology of the earth, when he handed that device he explained that Maria would call him the next day from the planet G44 and if he decided to answer the call, he would automatically be transported to the planet G44.
Nowadays it is not known, if Charlie decided to accept the call, the truth is that neither his parents, not his family, nor his friends ever saw him again.
