This story tells the story of Di Hong, an unlucky high school student who heroically saved a little girl, but at the cost of being hit by a car (so don't do good deeds). However, an elf with a bad personality happened to pass by and 'resurrected' the unlucky little girl with her magical ability. It's just that after Di Hong woke up, he found that his body was missing some small things, and his height was also smaller...
