"Well, technically, we have food," Min answered as he stood up from the ground and continued. "Rice balls from the town of Gyeoseong."
Rice balls?
Yuna's ears perked up.
She observed Min as he went several meters away from them and stood next to the horse, where they put their belongings. He grabbed several rice balls in a jute container and showed one piece of rice ball to them.
"Here it is," Min showed one rice ball to everyone. It was a literal rice ball, with no seaweed, tuna, bacon, ham as a filling. It was just plain rice rolled into a ball---great for travels and to stop from getting too hungry.
He took a bite and chomped it like it was the most delicious food in the world. The two princes stared at him with contempt as they clearly hated the fact that they would only have one rice ball for dinner.
Obviously, the princes were too pampered and only ate delicious and well-prepped meals during their stay in the palace.
