Two twins took a DNA test for fun, just to upload the video to TikTok. But when the doctor saw the results, he closed the door, picked up the phone, and dialed 911. Sophia laughed, thinking it was a prank. Valentina stopped laughing when she saw the doctor’s hands were shaking. “What’s wrong?” I asked—their mother. He didn’t answer. He only looked at my daughters as if he had just found a body buried inside my house.

Valentina wept with rage. “You invented birthdays for us.” “Yes.” “You invented a father.” “Yes.” “You made us twins.”

I lowered my head. “Because you two found each other before you found the world. You cried if I separated you. You ate if you were together. You slept with your hands touching. I didn’t want to break that.”
