Jongwoo:

Immediate stress, even if he doesn't have to be anywhere. He isn't outside for fun, he's here to get to the place then home so fast as possible. Though when he thinks on how he'll be longer away from THAT place he finally relaxes and starts to talk about random stuff to fill up the time waiting for the next bus.

Moonjo:

Outerly he's calm and okay, innerly he's raging and irritated. He likes to go stuff his way, have his schedule followed. So this bus leaving without you two makes him angry, even if you two are the ones who came late.

Say it's okay and he'll agree, smiling that there are always other ways to get somewhere, but inwardly he's blaming you for this mistake.

Junghwa:

A long 'aaah', shoulders slouching so hard she leans forward. She should have taken the car! She'll pull out her phone and try to see what other ways can get to the destination. If the next one comes soon she'll sit down with a sigh and wait. But if another way that is sooner she'll take your hand and hurry to that way instead.
