Since this place prohibits bringing foods, the sea environment is clearer than any other east sea points and there are many sea creatures. I hanged out with silver sharks and this point has very beautiful coral on the rock. When we checked after-pressure, Yumi Kim's pressure left 100 bar. She came suddenly and said maybe out of air so I checked that left pressure was 70 bar :) Since it was new equipment, she might be confused. I was also confused since it was a bit different from other pressure checkers. so I came up without safty stop. I will not forget about this happening :)
