This is already the 4th day, which meant that we have left Jeju Island. We barely spent in Jeju Island as it was purely visiting. The moment we touched down to Seoul, all hell breaks loose. There's nothing that we can control. For obvious reason, we overspent on the very first day. What kept us a lil bit sane was the very bit of sightseeing there.
We visited the National Folks Museum which located not exactly far from where we stayed.
