After Shen Niannian died, he became a ghost. He lived in an abandoned power distribution room on the top of the highest building in the city, hiding from the sun during the day and floating out to cause trouble at night.
A basketball flew up from downstairs and hit her on the head. Downstairs lived a boy named Jiang Yu who played basketball, listened to Canon, was afraid of the dark and had a tough talk. Nian Nian drifted into his room and didn't want to leave - he couldn't see her anyway, so she eavesdropped on him playing games and sneaked in to take a breath of Yang Qi while he was sleeping.
But ghosts have a shelf life. As the spirit decayed day by day, she began to appear, and he finally saw her. You can lie to yourself when you can't see him, but you can't do anything about it when you see him - she can't touch him, can't hold him, and can't even cover him with a quilt.
When the seven-day countdown began, she realized that some distance was not between life and death, but the inability to retain even the last bit of warmth.
The night she disappeared, he held his empty hand and called her name again and again.
Three months later, he designed a bridge connecting the two worlds. There was a canon sound in the middle of the night, and the basketball in the corner rolled out on its own, lightly knocking the toe of his shoe.
The ball skin is still a little warm.
He chose to believe that she had come back.
