I saw a Black person at the sauna today

‌I was startled to see a Black person with dreadlocks inside the bath tub
I was even more shocked when he stood up inside the tub
I could feel everyone in the bathhouse focusing their gaze on one spot
He was really tall, probably over 190cm. His build was massive, too.
He used the facilities very skillfully, doing the sauna, going into the cold tub, and getting a water massage.
We finished our sauna sessions at almost the same time,
and as he was getting dressed to leave, he took a Birak Sikhye out of the fridge, paid for it, and drank it.
The place was smaller than I expected. It seems to have become quite localized/Koreanized.
It was a bit mysterious.
