pinky promise

"Kook, can you pinky promise me something?"

"Yes of course, anything."

Taehyung bit his lip, oddly nervous to ask the younger this question. "When I get old, and nobody wants me anymore, will you pinky promise to stay my best friend forever?"

Jungkook smiled at the older's purely innocent request. Who was he to deny an adorable, wide-eyed, pouty Kim Taehyung what he wanted?

"Of course, Tae. I'll never leave your side."

Taehyung grinned, sticking out his pinky for the younger.

Jungkook twisted their pinkies together. "I pinky promise."
