Korean, this is why the language is hard to learn. Often or not, we don't even mention I or You in the conversational Korean.

Sarang Hae literally is "I love You" without putting word "I" or "You" I guess Koreans think that when they have a conversation, they don't really need to indicate you or I. So we kinda eliminate saying it.

But in the learning of Korean,

I = Nae or Na (must use with particles.. example>> NaeGa, NaNuen)

You = Nuh or Neh
