저 한국말 진짜 조금밖에 못해요. 아직 배우는 중이예요.
You know, just korean people dont have much of experience to talk with foreinger, so their laughing when u say some korean is just because they are (kind of) embarressed.
And im pretty sure if that Koreans were women, they must be thinking that your Korean pronunciation is cute because that's unnatural. Unnatural is not a bad thing, it sounds more cute becuase that is not perfect.
Dont worry too much and keep trying ! When u get used to it, you should be fine. Good luck !
