This is pure sugar. Such a cute, heartwarming and supersweet romance with some funny stories about their friends and families on top. The characters are loveable and divers and I especially like Nanako's dorky father somehow.
The animation and music are short, nice and simple but that's all it takes to tell these lovely stories.
It's kinda all about the Senryuu which is basically a form of short poetry which tends to be about human foibles and is often cynical or darkly humorous. The form is similar to haiku which is mostly about nature and rather serious. Naturally I had to google it since my knowledge about poetry is non-existent.
Anyway it is a very nice entertainment and I had to chuckle quite often. It's very enjoyable and thus recommended!
