Because of the last choice Kanade made, a mysterious girl named Chocolat came falling from the sky. It appears that Chocolat has something to do with the curse of Absolute Choice that anguishes Kanade, so he lets her live with him in his house. It's then that Kanade recieves a mission on his phone: to make his classmate, Yukihira Furano laugh. Considering the fact that she's cold, shows no emotion, and has a sharp tongue, this isn't an easy matter.
I have remembered that 
I really don't know anything.
Ich habe mich erinnert daran,
 dass ich nichts weiß.
He recordado exactamente 
cuánto es lo que no sé.
He recordado que realmente no sé nada de nada.
Je viens de me rappeler
que je ne savais rien du tout.
Eu me lembrei exatamente 
do quanto eu não sei.
