Hooray for the return of the Pancakes for Breakfast anthology! It seems that there are two more stories left.
I like how Nico is often portrayed as a cool and slightly bad ass character in doujins. As opposed to her usual adorably idiotic self
Agreed.
This seems like one of those stories where one person - Kotori, in this case - slowly falls in love with the other after months of living together platonically. It's nice. Sadly, it seems that this author doesn't have any other Nico x Kotori doujins besides this, I would've loved to see a sequel or even a prequel.
