And don't call yourself my big sis!
!ولا تعتبري نفسك أختي الكبيرة
Und bezeichne dich nicht als meine Onee-chan!
¡Y dejar de decir

¡Y dejar de decir
que eres mi hermana mayor!
Arrête de te prendre pour ma sœur !
E non definirti come mia "sorellona"!
E pare de falar que é minha irmã mais velha!
И не называй себя моей сестрёнкой!
