Kagura Hikaru had deviated from his usual route on the way home, which first alerted Kiryu Hina that something wasn't right.
He had been close to the station that would take him home, but he missed it.
At that time, Kiryu Hina just thought he wanted to buy something along the way and didn't take much notice of it.
She did not expect that his final destination would be this kind of place—a love hotel.
A love hotel is not a hotel.
It's about love.
This place charges by the hour, providing a space for couples to do "things."
As for what those things are, of course, they are what adults love to do.
The men and women who gather in such places, needless to say, have clear intentions.
So why were Kagura Hikaru and Kohinata Motoyo here?
"Mister Hikaru... Motoyo... what are you doing?"
At that moment, she asked this question purely out of curiosity.
What were they doing, why were they there, why were they so close together...?
She did not understand; she couldn't comprehend it.
