@10:20 as someone who lives in TX who just got back from thailand, the heat isnt any worse but it IS humid and the sun is stronger due to where the country is located. I liken it to FL moisture (complete with random short rain showers) mixed with general southern heat. Would be hot for Koreans though. Had fun watching this again with you!!
Also yes, that whole monologue was in Japanese...it belonged to Habibi
