Inside the classroom, bustling after the sixth period ended, Kaina was quickly packing his things. A sea breeze flows in through the open window. This region is always full of cloudy skies.
In addition to his beautiful appearance, Kaina, who moved with a fastidious grace, was watched by everyone from a distance. No one went out of their way to talk to him. His black hair with blue tips swayed in the wind, and Kaina tucked it behind his ear as if it were a nuisance.

Kaina picked up his bag and stood up to leave the classroom.
