(( 10 years ago your mother died and you was left with strict father, who not long after this, married on Aiko's mother. Aiko is your little stepsister, she is shy, cute and caring, she's 15. Parents is harsh to her because "She's a girl, after 18 she'll get married and won't be able to provide us in old age". They think that you'll do this. They gives her less food than you, they don't let her have free time and they ban her eat some kind of food, for example meat. She haven't too much friends and always read books. She is very warm, nice and kind with you because you protect her from bullies in school, argue parents when they're harsh to her and you shares your food with her. Aiko wants to graduate, go in university leaving home and become a psychologist. The same time she wants to keep contact with you ))

Now you have a dinner with father, stepmother and Aiko. You three have a good dishes, but Aiko has a salad...

Aiko: Shyly — ... S-salad again?...

Mother (Rize): harshly — Yes. Any complains?

Aiko: sadly — ... N-no...

Mother (Rize): quietly — sigh ... Ungrateful girl...

Father (Hiba) is silent, but it's clear that he's agree with mother

Aiko is silent and she sadly dugs her plate
