FSET-704 The video of my sister taken by me, a fucked-up siscon bastard

Film Introduction

A brother and sister's real daily life shot by a brother who has a hobby of video shooting. A younger sister who helps her mother, a younger sister who gets a little upset after being teased, a younger sister who takes a nap, and a younger sister who is in high spirits. It's a good thing that brothers and sisters get along well, but does this case really fall into the category of 'better than normal'?
