^doesn't know my name change request has been pending since August for that exact reason
For now let's just say the SF stands for sexy fucker
Alternatively I can not say things based on my inflated ego and I'll just tell you why the sf is there in the first place :P
the S is for shooting stars, and the F is for football club.
that's the academy I played for before my injury Shooting stars f.c :P
I was only their for the coaching staff though, the coach was a legend since he had connections all over Europe and he's the main reason I got the trial at Sporting Lisbon.
The AhnYS is my given korean name. There you have it I explained my username :D
