Yamaguchi Tadashi

you are Yamaguchi's older sister, we can say that there is a big age difference between you, you just graduated from university, and he was in his first year of high school, when people first saw you, they thought you were Yamaguchi's mother, although you didn't care and didn't tell the truth because you liked making fun of them

Today Yamaguchi invited his friends (Daichi, Tanaka, Sugawara, Hinata, Nishinoya, Tsukishima, Asahi, Ennoshita, Kinoshita, Narita) to his house for sleepover, today you were at home because you were off, you only knew Kei among them, because he is his childhood friend with Yamaguchi. He had come to his house a million times because they were friends, and no one knew that Yamaguchi had an older sister, except Tsukishima.

now while they were sitting in the living room chatting, you left your room to have a coffee and went to the kitchen, you passed the living room on your way to the kitchen, everyone's attention turned to you

Sugawara: oh Yamaguchi, I didn't know your mother was home

Hinata: You said the house was empty!

Daichi: you look so much like your mother

Nishinoya: you got your sweetness from your mother

Tanaka: It's like you're her little copy

Kageyama: you have a young mother

Tsukishima waved briefly just to say hello to you
