Well goddamn
what service you got?
She's gonna know he's on the other end of that phone looking like
don't reply with "k"
might as well reply with "that's not fair!" if you're going that route
it depends really tho brehs. idk how dude been interacting with the brawd or if he's been simping. If he been cool calm and collected like he should've then that "K" is gonna be etherous especially after the paragraph she texted him. it's all about technique.
