Dj = doushinji
Yea..isn't it more like a sequel plus their story is actually included in the manga
Yes, that's what I though too. Doujinshis are made as a continuation/extras/fanfiction of a story right?
So I think that this is a spin-off ( since this is another story for Yone Senpai) and not a doujinshi for Taka's story =)
DJ are simply self-published work, the author can continue the story on her own if she wants xD
Why is it a DJ? Isn't this a spin-off of Kataomoi to Parade?
