The ending bugged me a bit. I have a feeling I was supposed to know what Keiko was talking about, but I didn't because the story didn't compel to care about her past. Other than that, I liked Ran and Keiko's interactions. Four stars overall, and three for the unsatisfactory ending.
I will miss reading this manga ;~; It was so cute. I wasn't expecting to see "END" on the last page tonight. Farewell, Stretch! Thank you for all the good chapters.
