This drama makes you smile, this drama fills your eyes with tears, this drama makes you laugh and... This drama makes you think. It was such an unique drama and I am really happy to found and decided to watch this drama by chance.

The manga characters were so cute, I laughed so much to "laughing old man", I love relantionship between dogs and Akkun, I love Hara-chan's reactions to ALL foods. Hara-chan was so goofy, his exaggerated movements were so "real", since it is normal to not know how to behave normally for Hara-chan. I love his enthusiasm about EVERYTHING and his sincere smile so much.
The drama has 2 songs with same melody but different lyrics. And both of them are perfect. Akuma-san's song was so beautiful, I love her voice and the lyrics. Here the link is: https://www.youtube.com/watch?v=uhWsiSvIry8 (I don't know whether there is full version of it, but I couldn' find it.) And about second song... After watching one episode from Nakuna Hara-chan, you may start to sing "Desho? Desho? Desho?" part like me. The scenes which all characters in the manga world sing this song were so lovely.
Probably my favourite character is Akuma-san, because she looks so cold and scary but she is so sweet inwardly.
There is one thing that I want to change about this drama if I had a chance. I wish they pay more attention to support roles' love story.

By the way, yeah it is kind of romance drama but if you want to watch a drama full of love and romance, I think you should prefer another one. It would be better if you watch this one, when you want to watch a drama which is really different from other dramas that you watch before.
