grammar and word are totally wrong. I think Korean people can not translate that

I guess he means "가능하면 당신의 이름을 알고 싶어요." If possible, I want to know your name.

I'll give it a try - for you to see how awkward the text is ~ if it's not a joke, it looks like three or more separate parts. maybe some words or even sentences were deleted acidently before sending? it happends sometimes when I'm using my old notebook.. however, if you have some more text before or after this "sentence", it might be easier to guess what's missing. 가능한 = possible 메인 = main 당신은 = you, as for you, regarding you, speaking of you 당신의 = your 이름을 = name 알고 = know, and; or: knowing --> 가능한 .. 메인 .. 당신은 .. 당신의 이름을 알고 .. possible .. main .. you [are; or: do] .. know your name, so ..

@Heesob Park: Someone messaged me this

Where did you find that sentence?
