The whole story is being written in advance...
My name is Hinagawa Yui.
Sorry to disappoint you, but I'm neither the older nor younger sister of the original heroine, Hinata Ema, and I certainly can't be her younger brother.
I'm Hinata Rintaro's younger sister by a full twenty-five years.
In other words, I'm Hinata Ema's aunt.
Even so, before my niece moved into the Asahina apartment, my life was already dramatically full of Asahina men.
For example:
My first love, whom I broke up with two years ago, had the surname Asahina.
Seventh son, Natsume: ... =0=
Also two years ago, the amnesiac student who confessed to me had the surname Asahina.
Tenth son, Iori: ... (-_-)
The sexy "roommate" I met while studying abroad had the surname Asahina.
Fourth son, Hikaru: ... (^ω^)
After I returned home, the man I was set up with had the surname Asahina.
Second son, Ukyo: ... (^_^;)
Later, my life turned into this...
Asahina Asahina Asahina Asahina
Asahina Asahina
Asahina Me Asahina
Asahina Asahina
Asahina Asahina Asahina Asahina
