Story:
Based on the manga, this drama was told very well. The idea of having a human as a pet is completely surreal and that's why it was interesting to see how the drama would unfold.

Although this is not a comedy, there were still quite a few scenes that had me laughing. This drama takes an unique look into the current dilemas that career women have about love.

Acting:
Jun's acting was quite good, but I found him much more interesting as Momo than Takeshi. Plus his voice was kind of had this annoying monotone-ness whenever he was not the pet Momo.

Koyuki was also on and off, but mostly on. Sometimes I found her to be a bit too stiff, but that's forgiveable because I guess that how she wanted to portray the Simure character.

Music:
Passable music. It didn't detract anything form the drama, but it didn't add to it either...

Overall:
The story was handled very well and had me engaged the entire time. It's feel good and quite a fun drama. I didn't expect that. Overall, a very good watch. Recommend it!
