Soo-hyuk didn't open any of the wings options as he plans to sell it.
I think he wears the wings for its amplification effects. When he got the wings, he said something like, "Wow, these wings really stands out. It will definitely sell for a lot.".
He anticipated that it would sell well since it is legendary grade and could be used to show off (≧∀≦)
cant remember but were the wings has an option to make the user fly? i'm still waiting for soo hyuk to use it to fly lol
