At the beginning of the series, I actually really really like it. The conversation and bickering between Saki and Kouichi are funny but feel very real as well (in a sense of their domestic problems happen to general people). However, when the third parties (especially the novelist) come to the equation, the drama being draggy and cliché. EITA is shining on his comical performance without being too exaggerated, while Keiko Kitagawa gives just right proportion as Saki. Appropriate performance from other casts as well. The ending, IMHO, giving a fair resolution to every character.
