He would stare at his phone in hope that he receives a call.

Or maybe a simple hi as a text.

He would often call her; just to be met by an unreachable network, or just a message that pops up that she's not picking up.

And when he would text her?

Well, she would reply. After days, to be specific.

And mostly the reply would be;
"I'm fine Jungkook."
