too immature to be 33

Although I like the fact that the female lead is a 33 yr old virgin who writes smut for adult magazines, some of her actions are too childish to be believed. I guess this type of broad comedy isn't supposed to be realistic, but watching her let Cheol Soo believe that she is pregnant was annoying. The sister is also a major jerk, and I can already tell she will interfere, and be a seriously annoying problem in the future.

I'm waiting to see some great chemistry, but so far i'm unimpressed.
