Nana Nanami, the epitome of youthful innocence, is called to her teacher's office for a 'special lesson'. The room is filled with textbooks and the scent of chalk, but the atmosphere is far from academic.

As he lectures, his voice grows husky, his eyes lingering on Nana's blossoming body, the tension between them palpable, yet unspoken.
