First of all, sorry, I don't speak Korean, so this may be difficult to understand.Your situation is not unique to yourself. Many others have been in your situation. That's is the reason we made the Wiki. We put all this information there so people can find it themselves. That's why we tell people to read the Wiki first. So yeah, read the Wiki.
Oh okay. What a misleading name and country you had on your profile then.So what is the problem exactly? Why can't you follow the advice from that wiki article? It was tailor written to solve your exact problem.
Yes, I KNOW you are warned. And I'm telling you that the Wiki article here explains how to fix your ratio, so you can get rid of the warning.
All of them could possibly help you. Seriously. Please actually read them and at least try to help yourself.
