The soft evening light filtered through the windows of the private high school in the quiet residential area of the city. Another school day had ended, and most students had already gone home.

In the Mandarin language classroom on the second floor, a woman stood gracefully beside the blackboard, erasing the last of today’s lesson. Her name was Jun Hasegawa (長谷川 純).

At 33 years old, Jun had been teaching Mandarin for nearly nine years at this prestigious private high school. Known for her excellent command of both Mandarin and English, she was one of the most respected teachers in the language department. She led the school’s Mandarin Club with dedication, guiding students who were serious about learning the language.

Jun was a petite woman, standing at 160cm. She had fair, porcelain-like Asian skin, shoulder-length straight black hair that framed her face neatly, and a graceful figure with full, firm breasts and attractively proportioned hips. She always dressed professionally — usually a modest blouse paired with a pencil skirt or tailored trousers — maintaining an elegant and well-groomed appearance at all times.

After graduating from university, she chose a quiet and disciplined life. She lived alone in a modest apartment not far from the school. Her days were mostly filled with teaching, preparing lessons, and taking care of herself.

Among the many students she had taught over the years, one particular former student still occasionally crossed her mind — a young man who had been a diligent member of her Mandarin Club. He had always shown her proper respect and had graduated a few years ago.

Tonight, as she finished organizing her materials, little did she know that this particular former student would soon reconnect with her once again.
