I wrote Batman/Superman fanfiction.
Here is the summary:
For once, Gotham forgets to scream.
No sirens, no crimes, no chaos — just silence, and a city unsure how to rest. Bruce Wayne doesn’t trust it for a second. Clark Kent decides that’s exactly why they should enjoy it.
Dragged from the Batcave and onto a rooftop dinner date, Batman reluctantly discovers what peace looks like when shared with the man who carries the sky. Between overanalyzed dumplings, melted takeout, and confessions under unexpected starlight, the world’s finest heroes learn that even in Gotham, love can sound like laughter.
When dawn comes, Bruce doesn’t retreat into the shadows — for once, he stays.
