"I'll try my best, but no–"

"No promises, yes, yes, I get it, do you know how to say anything else? You've always said the exact same thing, "I'll try my best, but no promises", every single time I ask a favour from you," Jennie sighed, rolling her eyes in exasperation, already knowing there's a good chance Jisoo won't actually do it.

"You know me best," Jisoo replied quietly, smiling as she lazily got tugged.

"That's because we've been best friends for like ten years? I've been bugging you nearly every year to promise me that I'll be the first one to read your tattoo, and every y
