My Fat Wife Is an Alien Life

My wife always says that she is a slightly chubby girl, and I think she is just the right amount of cute. Until late one night, I found an encrypted photo album in her old mobile phone. It was filled with photos of her when she was thin, with gloomy eyes and bandaged wrists. The latest photo is from our wedding day - she is crying in front of the mirror, clutching antidepressants. I was about to continue browsing when a message suddenly popped up on the screen: "Warning: Patient weight is below critical threshold and life support system has been activated." There were footsteps behind her, and she asked softly: "What are you looking at?" I hurriedly locked the screen, but she smiled: "It seems it's time to tell you the truth——" "I'm not human at all."
