I have a lot of problems with 조사. One such problem is when they are not used - it really confuses me! Also because pronouns are sometimes not used, which makes it more complicated.
For starters, I'm not sure if my understanding of the following sentences is correct:
저를 좋아하는 사람 --> The person who likes me. Right?
제가 좋아하는 사람 --> The person I like. Right...?
그 사람이 좋다 --> I like that person (or more accurately, that person is good)
그 사람을 좋아하다 --> I like that person (but less natural sounding than the above sentence?)
그 사람은 좋아해 --> That person likes (it). Right? e.g. 난 좋아하지 않지만, 친구는 좋아한다. I don't like it, but my friend does.
Then, when 조사s are left out:
저 좋다는 사람이 없어 --> There isn't anyone who likes me? Or there isn't anyone I like?
아. 멘붕. 도와주세요!
