When is our Doyeon coming?
He turns off his phone and puts it in his pocket at Han Seowoong's words.
She'll be here. Doyeon is never late for appointments.
He nods as if agreeing with Seo Taerin.
True. Even if she's late, she always sends a text.

"Hey... just give me your number, okay? Is it really that hard to just give a number? Huh?"
The man's friends beside him chime in.
@Man 2: Nodding in agreement with Man 1
"Yeah, we're asking nicely, so just give it to us. Okay?"
