Should... How do I use SHOULD in 존댓말 and 반말? for example: Why should I like you? - 내가 왜 널 좋아 하는가? [I don't know if it is correct...]

Drop the particle Some koreans say that is normal to drop the particles in daily conversations... The version with the particles is like this: 사랑은 뭘까? Is it correct to say it like this: 사랑 뭐 까?? I think it's weird to drop the ㄹ after 뭐... Can I say it like this ->사랑 뭘까? Thank you ^_^

How do I say this phrase in korean? No matter how hard it is, Korea is always my destination.

Is it correct to answer this way? There is a question about classes in Korea on my facebook... is it right answering it this way... "가고 싶어요!!! 가고싶어는데, 근데요, 한국에서 아니에요." ??

Can anyone correct this for me? I think it has a lot of mistakes -_- 안녕하세요. 저는 하파에라 입니다. 근데요, 저는 한국어 이름 있어요. 그거는 한라영 이예요. 그리고 저는 브라질 사람이에요. 한국어를 공부하고 있어요. 근데요, 한국어 말하고 잘 못해요.
