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...!
And I'm lucky to be in the same class as you.
وأنا محظوظة بوجودي في نفس صفّك
Bin ich froh, dass wir
in eine Klasse gekommen sind!
¡Y tengo la suerte de estar
en tu misma clase!
¡Y tengo la suerte de estar
en tu misma clase!
et puis nous sommes
dans la même classe !
E sono fortunata 
ad essere nella tua stessa classe.
E tenho sorte de estar na mesma sala que você.
