A man in his thirties was standing in front of she-devil's grave, under everyone's watchful eyes, he dropped the flower to her coffin, his tone was full of ridicule. “Congrats on your death.”Next year he came, “I won. You lost to me and I will live well. Just rot in there.”Next year he came again, “I have a pretty girlfriend and I will marry next year. My life is good. Nothing to worry about.”Next year he came once more, “I will stop visiting and forget you! My life is better without you! See, I live well!”But he came again the next year and the years after that. People said he was hunted by his so-called arch-enemy. That even after death, the devil did not even let him go.He stood in front of her grave. His once handsome face had turned old and wrinkly.“Bei Sangyun, I cursed you. You are not allowed to rest in peace. You must be suffering there like me, right? You devil...”He might be the last one standing. But his life was the same as the dead's- lifeless and empty. He did not live well, he never once marry and his heart was never at peace.And it was all the fault of one person.*****Bei Sangyun was a big bully in high school.

However, his report card was there. With gritted teeth, the young boy opened it.However, what appeared was not a hideous thing as he expected, but a bright pink letter with a little heart sticker as a seal.It turned out, the surprise was scarier than a snake.Was this a new form of torture?Since then, Bei Sangyun relentlessly chased the young Fei Chuan until the two got married.******This is a story of rebirth.
