No reason or setting is needed. Cute girls and cute clothes. A beautiful yuri world just for the two of them. Sweet and sad... beautiful. Asuka loves Chiharu and Chiharu loves Asuka. Just those few facts make everyone happy in this Vivian-style lovey-dovey documentary. What's more, the package photo was done by Hitsujiku Ruton, who is well-known for his yuri photos!
