Ascetic is not to be confused with aesthetics. Just leave it to some obscure Korean movie to improve my English vocabulary. I watched Come, Come, Come Upwards (1989) last night, which is about the lives of female Buddhists and, of course, asceticism.
It's not my job to elaborate the difference between ascetic and aesthetics. I just wanted to point out I was forced to run to an English language dictionary while watching a Korean movie.
