Changmin didn't expect there to be a "later," but he nodded anyway. This was a random act of kindness that he'd decided upon merely on a whim. He could just as easily stepped around the man that hit the pavement and continued on his way. But he was helpful to a fault before and after work, he supposed, because when you spend your whole day being nice to patients, you tend to carry it over until the whole feeling of work wears off. At least, that was his experience.
But still, there was a possibility that it could happen, and he wasn't so sure he was entirely averse to it. Kyuhyun seemed nice enough. Maybe he would ask for his number and check in on him sometime.
As soon as he got a yes, he lead them over to a spot at the edge of the sidewalk where there weren't any cars parked and started signalling for a cab.
"If you've got any tea, I actually wouldn't mind taking you up on that," he smiled, finally waving down a taxi. As the vehicle pulled up, he patted Kyuhyun's arm gently before letting go to open the door and slip inside. He held out his hand again to help the other inside as well.
