I think your advice is very solid.
haha, I know these shows aren't realistic. I am just watching them for their entertainment value and to learn Korean.

This is my first time hearing the ending "으신건지" on a word.
Is it a suffix?
What does it mean?
Can this be added to the end of other words too?
I'd like to see some examples with other words.

@Huisook
I admire you using the occasion of asking me to make corrections to your response to me as a way to learn. That's really smart.

There are only three sentences that need minor corrections:

1) Do you realize the evil benefits of K-dramas?

The word "benefit" only has good associated with it, not bad.
The word you should use instead is "consequences".

Do you realize the evil consequences of K-dramas?

2) Your standards of happiness may become unrealistically high.

The word "standard" should be singular in this sentence.

3) I think one of the reasons why Koreans don't get married these days is the influence of K-drama and Korean entertainment shows.

The word "K-dramas" should be plural.
