On the day of the Tennomifune Academy entrance ceremony, in the class 1-7 classroom, Hanakoizumi Anne (Hanako), Hibarigaoka Ruri (Hibar), and Kumegawa Botan (Botan) are told by their homeroom teacher Kodaira-sensei that they are unfortunate and unhappy students.
The goal of the students of class 1-7, who are burdened by a variety of forms of misfortune, is to become happy.
The three girls have trouble accepting their circumstances, but they're immediately given an unexpected assignment...!
who can't even help a cat 
and already broke her egg.
التي لا تستطيعُ حتّى مُساعدة هرّة
وقد فقسَتْ بيضتها
der nicht mal einer Katze helfen kann
und bereits sein Ei zerbrochen hat.
No pude ayudar ni a un gato
y ya rompí mi huevo.
No pude ayudar ni a un gato
y ya rompí mi huevo.
che non riesce a salvare un gatto
e ha già rotto il proprio uovo.
que não consegue nem ajudar 
um gato e já quebrou seu ovo.
