Slowly, he reached past the button and clicked Delete Scene .

Leo fell backward off his chair. The sphere hovered in the air above the laptop, rotating lazily. It was no bigger than a golf ball, but it was there , real and solid, casting a faint shadow on his desk.

“Stupid update,” he said, but he clicked anyway.

Real things. His things.

He picked it up—it was solid now, cool like glass. On its surface, a single word appeared in faint, glowing letters:

Paint 3D’s toolbar flickered at the edge of his vision. A new option pulsed: Below it, in smaller text: Warning: Changes affect original source.

The image loaded into Paint 3D. He selected and pressed Animate .

Leo understood then. This wasn’t just a drawing tool. It was a sculptor of reality. Whatever he painted in 3D, animated, and believed hard enough—it became real. For better or worse.

The living room dissolved like sugar in water. He was back in his chair, the laptop battery at 3%. The bird was gone. The tree was gone. Only the first sphere remained, sitting quietly on his desk, dim and cold.

“Hi, future me!” the model said in a glitched, cheerful voice. “Wanna build the spaceship again? Mom said she’d bring pizza later.”

Leo’s throat tightened. “She’s not coming,” he whispered.

“You have got to be kidding me,” Leo whispered.

The screen blazed white.

He wanted to see the limit . So he clicked and chose a photo from his desktop: a family picture from two years ago, before his mom left. His father’s arm around him, both of them smiling in front of a cheap birthday cake.
