What's the difference between ㄹ게요 and ㄹ께요? I've been wondering about this for a while now. According to what I learned, ㄹ게요 is used when we talk about a prediction, a plan or even an unconfirmed "truth". And ㄹ께요 is used to express a promise, a well-thought plan, it shows the sureness of the speaker. But as for this sentence "항상 응원해 줄게요" - I will always support you. I think that it would be better if we use ㄹ께요 instead of ㄹ게요 cause... well, the sureness. But I have never seen people use ㄹ께요 in this case, and it kinda makes me wonder a lot. It would be great if someone can help me understand more about these two grammars, thank you ^^
