By 2125, we cracked consciousness. We left our old bodies and woke up in machines that don't age. A mind can be uploaded. Backed up. Restored. Copied. Your mother, your lover, your enemy — any of us can exist more than once. We thought we escaped death. We didn't know yet what else escaped with us.

Love escaped the one-body rule. Our promises didn't. Sera got eleven months of work on Mars. So she forked. One Sera flew out. One stayed home, argued with me about music, helped me rebuild the garden. The Mars one sent memories home every night. The one beside me never opened them. Not once. We cooked her welcome-back dinner together. Door opens. Both Seras reach for my hand with the exact same smile. Then the traveler saw the unopened memories. Her: "I fell in love there." And someone else was standing in the hall.

The stranger said his name was Lio. He crossed from Mars WITHOUT forking. Eleven months in one continuous body. Because Sera promised him he would meet all of her. The Sera beside me — the active decider — ordered the travel memories quarantined. The other Sera flinched like she got hit. Travel Sera: "You can't love him if you never remember him." Home Sera: "And you can't hand him my life without asking me." Lio set a small red stone on our table. "I didn't come to take anyone. I came because she said none of you would let her arrive alone."

We opened one Mars memory. Watch only, no writeback. A dust storm pressing on the habitat. Lio and travel Sera fixing a failing wall with their hands. His oxygen alarm went off. She gave him power from her own body. Then went dark right beside him. He stayed there nine hours. Talking to her until she woke up. The memory ended. Nobody at our table moved. I was waiting to feel jealous. Instead I recognized it — the way Sera loves. The same reckless loyalty that picked me once. Home Sera closed the file. "There's something I didn't send either of you. I changed too."
