Finder Goshi no Ano Ko

Hajime, a girl who can’t seem to properly express her feelings into words, is worrying all on her own about the preparations for the cultural festival. This will be the last festival for her film club. There’s always been things she’s wanted to do for the festival, but like last year, she’s given up and the festival will probably end without her doing what she wants to do.
That’s when she meets Kei Ichinose, another student at her schoolー
