Hello somebody - 누군가 (누군가 오고 있어요 - somebody is coming) with 'I think' it could be a little tricky Literally translated 'I think' is 생각해요. However it is not commonly used and Koreans usually say 'it seems like' (i've learned that part of a korean culture is that they dont like to be too direct) so to say 'I think you dont like it' you need to say 안 좋아하는 것 같아요. To say 'something happened' you need to say 뭔 일이 생겼어요? or 무슨 일이 생겼어요? Hope this helps ^^
