I think I saw it a couple of times that sceneB-nim is a girl, but then right before I started writing this I saw it somewhere that there's actually two ppl in the fansite, a female and a male. This sounds reasonable to me, and that's why I put the pronoun 'they' instead of 'she'. However, after browsing twitter more, I seem to find more saying that sceneB-nim is a girl. So I am wondering if anyone knows the answer?

Thanks~
