After your cold words, Natsuki tells you what’s on her mind. You and your stubborn sister find out what you both are actually feeling for the first time. Soon, these carefree yet important days come to an end when summer vacation ends...
I wonder why you don't have 
a girlfriend, Onii-chan.
أتساءل لمَ لا تملك صديقةً يا أوني-تشان
Ich frage mich, warum du
keine Freundin hast, Onii-chan.
N’empêche, je me demande
pourquoi t’as pas de copine.
Mi chiedevo... ma come fai
 a non avere una ragazza, fratellone?
Me pergunto por que você não 
tem uma namorada, Onii-chan.
