Please, Don't Let Go

SOULMATE AU:
If soulmate A is older and they turn 21, they'll be able to hear soulmate B's voice in their head. Once B turns 21, one will appear in front of the other whenever they're asleep (ex. A appears in front of B when A is asleep / both will meet in their dreams if they sleep at the same time).

"Let's make a pinkie promise!" He stared at me in disbelief. "To make sure that we'll still see each other even after all this stops."

"Okay. Though I doubt we'd actually need to do that," he agreed while linking our pinkies together.

"Why?"

"Because I don't think I'd be foolish enough to let you go."
