I wrote Batman/Superman fanfiction.
Here is the summary:
For two days, the world goes on without Superman. No sightings, no messages—just silence. Bruce Wayne tells himself not to care. He’s handled alien invasions, godlike beings, and Gotham rush hour. But the absence of one man manages to unravel every layer of calm he pretends to have.
When Clark finally reappears—smiling, soot-streaked, and completely unaware of the panic he’s caused—Bruce’s carefully buried worry comes to the surface. What begins as a sharp exchange over communication habits turns into something quieter: a conversation about fear, control, and what it means to love someone who flies into danger every day.
Between arguments, awkward humor, and a rooftop kiss interrupted by the Bat-Signal, The Clark Kent Disappearance is a story about two men learning that “I love you” can sound a lot like “You could’ve texted.”
