Masaki dreamed of becoming a painter and helped out at the art class hosted by his father. However, he grew anxious about his own drawing skills, and daily practice began to feel like a burden. One day, a new student named Kana joined the class. Her presence was like a figure stepped out from a painting—her translucent skin and graceful aura deeply stirred Masaki's heart. Soon, she volunteered to be a sketch model, boldly baring her body. Overwhelmed by both confusion and arousal at her daring act, Masaki found himself completely captivated by Kana's beauty. From that moment on, his life became consumed by intense, unfamiliar emotions.
