In the third installment of "My Little Sister," Kotone Mei-chan appears as the sister! The real daily scenery and conversations between a brother who only posts videos all the time and his sister are way too realistic!! A work that you could watch forever just with the natural brother-sister conversations, where the sister, who scolds him with words like 'stupid' and 'disgusting,' ironically makes it look like an expression of love for her brother. Please carefully observe the line that must not be crossed, born in the daily life of the siblings
