Two objects lay in Lin Qiao's white coat pocket:
- The user manual for Li Yunzheng's artificial heart (every margin crammed with her name)
- A faded crabapple photo (new inscription on the back: *"We weren't specimens—we were survivors"*)
When she transfused her Rh-null blood into his IV, the monitors screamed—their cells in the petri dish merging like reunited DNA strands.
"Funny thing," Li Yunzheng caught her blood-drawn hand, "the scar behind your ear? I made that with a toy knife when we were three."
Lin Qiao froze. This memory didn't exist in her mind.
"Side effect of MN-07." His lips brushed the scar. *"Transplanted memories... always take root."*
At sunset, they stood shoulder-to-shoulder against the rooftop ledge. Beyond them, colored lights blinked atop the new children's hospital built over the Bay Project ruins. Li Yunzheng produced a coin—the very one from their courtroom meeting.
"Heads you kiss me, tails I kiss you."
The coin spun midair before wedging itself upright between floor tiles.
Lin Qiao yanked his tie with a laugh: *"Seems fate's letting us choose."*
