During the cultural festival, Izumi-kun and Kamiya-san have a good time chatting as they share library duty. Then Nekozaki suddenly comes along and takes Kamiya-san away to see Shikimori-san. When Kamiya-san hears what Shikimori-san wants from her, she readily agrees. Later, when Kamiya-san returns to her classroom to help with her class's festival project, her elegant look draws a crowd of classmates and guests around her. As she drowns in all the noise, a certain someone suddenly comes to mind, and she breaks away from the classroom.
This was my fault. 
You shouldn't have to help me.
كانت غلطتي. لستِ مضطرّة لمساعدتي
Obwohl das meine Schuld war,
hilfst du mir beim Aufräumen.
que te pongas a recoger
cuando es mi culpa.
que tengas que recoger esto
por mi culpa.
La colpa è solo mia
 e tu mi stai aiutando a rimettere in ordine.
A culpa é minha, mas acabou
tendo que me ajudar.
Это всё я виноват.
