You're welcome!.

Great! Just don't forget pural at the end of "Soap Opera" (Soap Operas) And one tip for common English, it's more common to call a 'Soap Opera' a 'Drama' (^_^) Hope that helps! (:

Native speakers have a wealth of potential responses to use in any situation. That just comes with exposure to the language in many different situations. It's not even necessary to go to that country to get the exposure. Look at the website http://antimoon.com/ about how they learned English to a very high level of fluency without leaving their home in Poland (I think it was Poland), if you want. Parts of this site have even been translated into Korean it seems.

But it would never be wrong or awkward to say "you're welcome."

As for me I actually do use you're welcome a lot. Although more often I probably say either "no problem" or "yep!" if it's more casual ^^

I mostly use "sure"...I think "you're welcome" is nice though, it's much more sincere. it's not used so much since people are lazy, which is a shame. :)
but the korean equivalent 천만에요 isn't used very much either in korean, no?

I use "you're welcome" a lot ^^ Also, "it's all right".
But yes, like previous commentators have said, there are lots of potential responses to use, and it's never awkward to use "you're welcome".
It can also depend on the setting, formal or informal. "You're welcome" would definitely be more appropriate then "you bet" or "no sweat" in a formal setting.
