how do you spell korean names

Sometimes I wonder what everyone else names the MC in Mystic Messenger. Do you go for a Korean name? A screen name? Something different? I’ll admit that I went for a Korean-ish sounding one? I mean, the names are real names from the culture but I’m not sure if they sound good or have a good meaning/it’s how  it’s actually spelled but I did it.

What did you name your characters?
