It takes years for Japanese anime boys and girls to send text messages.

Makoto Shinkai's The Voice of the Star.

In 2039, the earth survey team was attacked by Tarsian people on Mars, which led to the fate of complete extinction. Seven years later, in 2046, the earth people have established a powerful cosmic army by using the technology obtained from Tarxian, initially defeated Tarxian in the near earth circle, kept the safety of the earth and began to organize expeditionary forces to fight back and turn into a state.

Hosinokoe, a junior girl, and her classmate A Sheng are lovers. Every time after school, Meijiazi always rides A Sheng's bike home and talks about their future on the road. On a beautiful evening after the rain, Meijiazi looked at the white spaceship rising slowly in the sky and whispered to Ah Sheng, "I'm going to take that spaceship." It turned out that she had been chosen as the driver of the combat robot and was about to set out to pursue Tassian.

14-year-old Meijiazi embarked on a journey to the universe. After receiving intense and short-term training in the Mars circle, she devoted herself to the battle against Tarxian. After the fierce fighting, it has become a compulsory course for the United States and Canada to tell each other their feelings by SMS. However, with the increase of the pursuit distance, the time to send emails is getting longer and longer. One day, January, half a year, a year ... when she was promoted to high school, there was another girl who admired her, but because of Meijiazi's email, he refused that girl on a snowy day. Both of them fell into a lonely wait. Clouds, rain, weeds, classrooms after school, messy telephone poles on the roadside, asphalt roads painted with white lines ... everything that can be seen everywhere in the days together has become something they miss. Meijiazi from outer space said, "Maybe we are the first lovers separated by the universe." A Sheng replied: "Maybe, missing can transcend time and distance."

Finally, in a fierce battle, the earth army had to move to Sirius alpha and beta galaxies 8.6 light years away from the earth because it was outnumbered. On the beautiful grassland of Sirius, in the sun rain, Meijiazi sent this message to Ah Sheng: "24-year-old Sheng, I am Meijiazi of 15 years old, and I found that I still like you very much." This time, it took 8.6 years ... the fierce battle began again, and the United States and Canada threw away all their emotional burdens and devoted themselves to it. I watched my warship fleet perish together with the enemy, and the last large warship of the other side was about to crash its only surviving main ship. The United States and Canada desperately got rid of the interception of enemy small fighters and tried their best to kill each other's warships. The powerless robot floated in space, and Meijiazi smiled at Sheng in the distance with tears in her eyes: "Sheng, I am here."

Eight years later, the situation of the space expeditionary force spread to the earth, and only one warship would return to the earth. On this day, A Sheng, who has joined the army, also received a text message from Meijiazi eight years ago ... He looked up at the blue sky and responded to his invisible lover: "Meijiazi, I am here."
