Rika moves in with Naoya and the others, and insists that sleeping in the same room with him in a non-sexual fashion should be completely permissible. Naoya agrees, but only if all the girls get to take turns sleeping in his room in a non-sexual fashion.
If I'll be sleeping with 
Mirika-san on some nights,
،إن كنت سأنام مع ميريكا-سان في بعض الليالي
Wenn ich mit Mirika-san
in einem Bett schlafe,
Alcune volte dormirò con Milika,
Se eu for dormir com
a Mirika-san algumas noites,
