Singer turned actress Son Dambi believes "Ratings are just a number...". It might not matter if you're hot, but in this dog-eat-dog world of the entertainment business, ratings are everything. Son Dambi's drama 'Dream' isn't doing too hot and only managed a 5.4% on it's first episode. It looks like she's depriving herself of sleep just to receive acting lessons though. But I don't know how much better you can get at acting through some crash course lessons. Better to get some sleep and look hot so that people will have some reason to watch the drama at all. From Son Dambi's side they mentioned "From the first time Son Dambi decided to try acting, she decided that ratings would be just a number for her. Because of this, she will visit her acting teacher whenever she has time and will go practice. It isn't just Son Dambi though, all of the staff are working hard." Girl, just stand around looking hot, I'm sure that will bring in a lot more ratings than your attempt at acting.
