This OVA feels like screenshots from manga/anime. It is basically just an ad for the manga series and anime. There´s no movement in the scenes and only transitions are used.
The story is shorter version of the anime and it goes through Yuukure´s and Risa´s realitionship. The artwork is nice. Compared to the anime there´s zero action in the clips and it is boring. Gladly each clip is only around 2 minutes long. It is just a recap.
The clips don´t leave anything interesting for viewer to read the manga. It is basically just like "We are such a cute couple and we love each other so much." Compared to the other anime the characters here are shown as very uniteresting and you don´t learn much about them.
I reccomend watching the other version, if you don´t want to read mang. These shorts are just wase of time. The pictures in this anime are nice, but they would be better as a poster, online ad or GIFs rather than OVA.
Fans of Nagareboshi Lens might enjoy this but other viewers won´t.
