The meaning originally comes from the old Chinese. Each individual has its own meaning. Maybe I am wrong but if I am not, you are looking at it wrong. Before puting two syllables in one word, we consider picking usually two syllables that we want to express the person. One of downsides is that sometimes some names do not sound pretty(weird sometimes) even though it says meant well for the persons. Therefore some parents want their kid names to be pure Korean words that come from seasons, flowers, and so on. I know some girl named '가을' (fall).
And actually there are some more you could find it interesting. Like my name is woo-youl and my brother's is jung-youl. If there was another brother, his name would have been someting - youl. See the pattern here? This is a traditional way that people still follow, but not all of us. You can look it up and find something like this about Korean name.
And the botttom line is this. You don't have to worry about the meaning of your name. Since no one find it for you, you can simply find it for yourself. For example, one of 'hae(혜)' means 'wise' and one of 'in(인) means 'person.' Good luck
