Having idle conversations and living with someone. Natsuki reminds you of these warm feelings you had forgotten about after living alone for so long. Natsuki works really hard for you, and in return, you try to reward her with a beautiful view...
Jeez. Laughing at your little

Ehi, è cattiveria prendere in giro 
la propria sorellina!
Rir da sua irmã é muita maldade.
