Why do you think Food Eating videos are popular in Korea?
Some Koreans may watch these videos to feel less lonely if they eat alone in their room, or live on their own since these videos are filmed in the first person view, so it is almost like you are eating with the person in the video.
I also read comments where some people relax when watching these eating videos because the sound from food chewing, and visual eating movements give them tingles which are relaxing feelings all over their body sort of like when someone tickle you in a relaxing way.
