A text message popped up in the class group chat. A student had been in a car accident and had been rushed to the hospital. She urgently needed a donor with a rare RH-Negative blood type. Wanting to help, I went to the hospital and donated 800 milliliters of blood. Afterward, I passed out from blood loss. When she woke up, she claimed she was pregnant and said the baby was mine. Everyone accused me of crossing a line despite being an educator and professor in college. They said I had slept with a student and got her pregnant. I went to confront her, but she acted like she was the victim. "Your blood is in my body now, and in the baby's body too. What's wrong with saying the baby is yours? From now on, my baby and I are depending on you. You'd better take good care of us and make sure we don't suffer, or I'll sue you for seducing me and dumping me!" Furious, I shoved her. She rammed her stomach into the corner of a table on purpose and miscarried. The internet decided I was a scumbag who had killed the baby on purpose. "How can someone like that exist? How can someone like that teach at all!" I lost my job. I was doxxed and harassed over the phone. Someone even threw acid on me and destroyed my face. I lost everything. My wife, who was eight months pregnant at the time, believed me and defended me, only for the internet to turn on her too. They accused her of helping a monster to hurt others. The stress caused her to have a serious hemorrhage, and she and the baby both did not make it. Crushed by guilt and grief, I jumped off a building and killed myself. That student, however, profited from my tragedy and became an influencer with a million followers overnight. When I opened my eyes again, I had regressed to the day I saw the message in the group chat.
