Detained for 38 hours in South Korea (Jeju Island) & China. We landed in Jeju Island, South Korea excited and ready for our trip. Within a few hours, everything changed. We were denied entry and taken to a holding area. No proper explanation just told to wait. And we waited. Hours passed without clarity. They kept us in their detention centre (it was similar to a jail with no sunlight & no access to outside) and also gave us jail food. Nobody told us what was going to happen. They blackmailed us
