Nishikata is at the mall to buy the latest volume of ・00% Unrequited Love・when he runs into Takagi-san. 
She wants Nishikata to help her pick out a bathing suit, but Nishikata is too embarrassed to be seen with her. 
Suddenly, Nishikata hears a familiar voice...
That's none of your concern!
!هذا ليس من شأنك
Das geht dich nichts an!
¡Eso no te incumbe!
¡Eso no te incumbe!
Mêle-toi de tes affaires !
Questo non ti riguarda!
Não é da sua conta!
Не твоего ума дело!
