My memory of this one was that it was on the short and somewhat messy side, but with an incredibly adorable protagonist.
Having reread it, I can see that it has the scaffolding in place for a much longer manga. It is as if chapters 1-2 are the introduction and chapters 3-4 are the conclusion, but the many potential stories and developments in-between never had the chance to be told. Oh, and I've also confirmed the protagonist really is every bit as lovable as I remembered her.
