Limit to 500 words. I am Xu Shaofeng, male, 25 years old, graduated from the Computer Science Department of the university. He was supposed to be a promising young man, but once he traveled through a lifetime of regrets, he fell in love with my sister who was obsessed with my bad luck (Light of Bad Luck). Looking at the ancient times where productivity was obviously lagging behind, I wanted to rely on The advantage of civilization with a history of five thousand years is to be a promising young man and repay the kindness of my sister's upbringing. But, but, but, I shivered and looked at the two soft lumps on my chest, and looked at my sister's flat figure that is comparable to an airport. Damn, what on earth is going on? After accepting the reality, I still have to let my sister support me in this ancient time, (face covering), Coco, but why on earth is this, goddess! My goddess, why are you throwing yourself into my sister's arms one by one, just when I am trying to save these goddesses from going back to the road of no return, huh? You handsome and scumbag men, don't hang around in front of me one by one. I am a man, even though I am not pure now!
