Bold = Anytime, anywhere
Underline = I don't mind writing, but I ship them 100%
Normal = I ship only, but don't write (unless necessary)
Strikeout = I do not ship, I do not write 

NOTE: the left side will be the girl, and the right side are the guys who are often paired with her. say if it was
Jessica: Jonghyun | Onew
it means that I ship Jessica with both Jonghyun & Onew and I can write them anytime, anywhere :)
pairings that are not inluded, I do not ship, I do not write, but I don't bother telling, because the pairing is not very popular
