High school student Yuta Asamura begins living with his stepsister Saki Ayase and her mother due to his father's remarriage. Both Yuta and Saki, who hold cautious values regarding relationships between men and women, agree to live with an appropriate sense of distance between them.
My mom can never say no, so she bought 
everything that they recommended to her.
أمّي لا تقول "لا" أبداً، لذا اشترَتْ
كلّ شيء نصحوها به
Mama kann nicht nein sagen und hat einfach
alles gekauft, was ihr empfohlen wurde.
Mamá no sabe decir que no.
Mamá no sabe decir que no.
Ma mère ne sait pas dire non,
elle a pris tout ce qu’ils proposaient.
Visto che mia madre non riesce mai a dire di no
Minha mãe não sabe dizer não, então
comprou tudo que recomendaram para ela.
Мама не может никому отказать,
вот и купила всё, что ей предложили.
