hey, is this a oneshot? it says it is but it has like 2 volumes. one shots are like half of a volume 1 at most. so does that mean its continued?

I believe the oneshot Boy Meets Girl, Girl Meets Boy is a oneshot of two chapters, which is contained in the anthology Change H.

Here's the post from the scanlator that states there is a second part.
