[DKP Survey] f(x)'s Sulli and Go Ara are twins?

Well,i have just finished watching SBS drama Heading To The Ground a few days ago,i know that the drama has finished its airing for quite sometime already and i am sorry for being outdated.

Well,straight to the main point,seriously i think that the actress in the drama Go Ara does resemble f(x)'s Sulli,of course this is only my personal opinions,so i need to ask the readers of DKP whether you agree with me or not.

So what do you think,do they resemble each other?
