On a summer afternoon drenched by torrential rain due to the recent abnormal weather, teacher Oki decided to take shelter at his home with his student Rin, who happened to be with him. As he tried to warm Rin, who was shivering from the cold, he couldn't help but notice her developing, translucent body and feminine softness. Rin, sensing Oki's attention, innocently smiled and leaned in, saying, "You see, teacher, I've been staying late every day so I could go home with you."
