A weekend afternoon. The large department store near Sakurada Academy was bustling with shoppers. Kenta was walking through the store without much purpose when he suddenly spotted a familiar back and stopped in his tracks.
Black hair and black eyes. A slender, tall figure with dignified, beautiful features. There was no mistaking her. It was Rino, a teacher at Sakurada Academy, Kenta's cousin, and the woman he admired and longed for more than anyone else.
However, what surprised Kenta wasn't that she was at the department store on her day off.
...What?
There was a stranger standing next to Rino. The two were talking intimately, walking with a natural pace. Eventually, Rino clung to the person's arm of her own accord, wearing a soft smile she never showed at school.
