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.
Don't make yourself at home just 
because my parents are away!
Nur weil meine Eltern nicht da sind,
 heißt das doch nicht, dass es nun dein Haus ist!
¡No te sientas como en tu casa 
solo porque mis padres no están!
¡No campes a tus anchas solo 
porque no estén mis padres!
Mes parents
ne sont pas là,
Não se sinta em casa só porque
 meus pais não estão!
