Miyazaki Nana in her high school years only looked blankly at the back of the fair-skinned slim girl with waist-long straight black hair. The minute her math teacher during her first period, Mr. Kobayashi, recognizing her presence, he immediately acknowledged her name.
"Oh, Nana-chan. Glad you're here," says the teacher enthusiastically, making Nana's eyebrows furrow at him.
It was at that moment when the black-haired girl turned around to see who is this Nana-chan that her teacher called just now. By the time she came face-to-face with her, she was only greeted with her bored stare and blank expression plastered on her cute face.
"'Sup," Nana greeted nonchalantly.
"Eh? This would be my tutor? Are you kidding me?" The girl blurted out of shock. "She is much younger than I am!"
Mr. Kobayashi only frowned before he scolded her to shut her mouth and immediately shifted his gaze back to Nana.
