This custom seems to go back to the level of beliefs like, if you call your child's name, a demon can get it. It also seems to tie in with beliefs like Sang-sik's (on Who's My Love), that you shouldn't say you love someone because you'll "make it not special"--on other modern dramas, saying "I Love You" seems very, very, VERY carefully meted out. So, if you say someone's name all the time, it means you don't think they are special. Finally, it may have connections to--oof. I had an excellent idea, but I've lost it now. Maybe someone else can tell me what it was.
From Dae Jang-geum: Sun-dol: "Are you trying to dry me up and kill me? Why do you say the same things over and over every day? Rather, come and hit me once! Aigu!" But then: Dr. Lazarus: "By Grabthar's hammer, by the suns of Warvan... You shall be avenged."
Yeah, that was funny! And true. I don't know if you know it, but Bae Yong Joon underwent a physical transformation last year, employing a 4-month regimen of rigorous diet and exercise to become incredibly buff. He then published a book of photographs with him looking astonishingly muscular. He did say that he ate a lot of chicken breast, and young men in Korea were following his regime. It's my understanding that Joon just did it as a temporary thing, sort of just to see if he could do it. But maybe you already knew that.
I don't see skinny In-chul getting too far with that! But I think he's cute the way he is. I'm with Mi-jung on that.
