Writing in 3rd person is very much easier for me. 

C.D is going to be written in 3rd person, but from Baekhyun's pov, I guess?

So - do you prefer:

a) a named OC, description and all; 

b) unnamed, kind of vague, 'the girl' sort of thing? (seeing as CD is probably gonna be v short)

I'll add a poll when I figure out how, LOL
