Not sure if it's Korean or Chinese, people with abilities, MC has white hair I think. There is also a purple hair guy who behaves like a villain but is protecting him. There are also few more people protecting him. They are fighting other people with abilities. I think the MC has a good friend but he died, and he probably has some problems with his body. I think one member of the group protecting MC is a girl who takes her brother's place. (Not sure about this one since it might be a mixed up from other webtoon)
I know my explanation sucks and probably lots of work with similar premise like this but thank you for your help!
