Childhood best friends AU+:｡.*

"I'll find you."

The massive universe they live in with countless worlds and undiscovered properties of the unknown, young Nicholas Armstrong or Sapnap still hasn't given up on finding his childhood best friend who is so dear to him. He's grown a lot, learned to control his powers and abilities now, like the fire. He traveled through kingdoms, towns, countries and he's willing to go to another world if it meant finding his childhood best friend. Wondering if they still remember him, doubting, overthinking. That's him sometimes. But he made a promise to himself.

"I'll find you."

The day they got separated, he swore by his heart.

Desperate, determined, and persistent.
