Then, who was that girl from earlier?
She is your younger sister Nayuki.
Did Akiko-san really lose her memory!?
Then, is it ok to treat her supposing she is a high school student?
Errr... Yuuichi-san?
Errr...
Moreover, didn't Nayuki go out and it's just me and Akiko-san in this house now!?
That's so!
Your name is "Minase Akiko", a 17 years old high school girl!
And I'm your cousin "Aizawa Yuuichi", and we are mutually in love boyfriend and girlfriend.
Oh, that's how it really is!!
F...fufufu...
That's so...
This is a chance that God gave me...
Yes, that's right.
I like Akiko-san...
"A high school student like me"!!??
