Sueharu thought he had carried out his plan to perfection at the confession festival, but what he thought was just a little idea of his own ended up involving everyone around him, and when he confessed to Kuroha, she rejected him. Kuroha answered his feelings with a hard no, and Shirokusa had to hear him say that he "was" in love with her, but no longer is. And now, a newcomer is about to make this love triangle even more complicated...
Oh, I remember now! 
The key fell from the sky!
!تذكّرت الآن! سقط المفتاح من السّماء
Ah, jetzt erinner ich mich wieder!
Der Schlüssel ist vom Himmel gefallen.
Ah, sí, la llave cayó del cielo.
Ah, sí, la llave cayó del cielo.
Je me rappelle,
les clés sont tombées du ciel !
Oh, ora ricordo! La chiave è caduta dal cielo!
Ah, é verdade! A chave caiu do céu!
А, теперь я вспомнила! Ключ упал с неба!
