My Girlfriend's Sister

Min-Hyuk has always harbored a secret attraction to his girlfriend’s older sister, a strikingly mature and alluring woman whose presence constantly tests his self-control. Despite knowing the boundaries he should maintain, he finds himself inexplicably drawn to her every time they are in the same room. The delicate balance of his relationship is shattered one fateful day when he accidentally stumbles upon her in a deeply intimate and private moment. Rather than averting his gaze and walking away as any respectful partner should, Min-Hyuk finds himself completely paralyzed by the sight. The intense temptation overwhelms his better judgment, erasing the guilt he feels toward his girlfriend. Instead of retreating into the safety of propriety, he makes a bold and irreversible decision, stepping forward to offer his assistance. This single impulsive choice plunges him into a tangled web of forbidden desire, threatening to destroy his current relationship while dragging him deeper into an illicit entanglement with the one woman he was never supposed to touch.
