A grammar question in Beginner Lesson #167

[watermen]

I find these grammars difficult to understand despite knowing the meaning.

ほんの遊びのつもりが、私、結構まじになっちゃったみたいのよね。あー、私は一体どうしたらいいだろう。


1. I know the meaning of 結構 and まじに, but when they both come together, I don't quite understand its meaning.

2. What does のよね mean here?

[Javizy]

It just means 'quite/pretty serious'. のよね is just a feminine version of よね, which you use to speak emphatically about some sort of shared knowledge and ask for agreement at the same time. Kind of like the tag question 'haven't I?' in this case, I guess.

Thanks for your explanation, I think I understand now.
