After the first episodes I thought I was gonna give this "Shimobee" a pretty high grade, 'cause it started very well, managed to be really hilarious here and there, and was altogether very entertaining.
The second half of the series, though, was more or less the fair of déjà vu (the "terminal illness" trope can produce gems like "1 lt. no Namida" or "Neko", but it can also result annoyingly trite and cheesy, as it was the case here, imho) and that made me lower the rating considerably.
Still, both Shiraishi Sei and Yasuda Ken deserve a standing ovation: the former is not only a gorgeous woman, but also a marvelous actress; and the latter is simply amazing, I honestly don't know many actors who would've been able to pull this off!
The music was also really nice.
Overall, and despite the not-so-great script, a pleasant watch.
