After enrolling in college, my girlfriend suddenly changed her behavior following her club's freshman welcome party. When I confronted members of her club, they handed me an SD card. It contained detailed footage documenting everything from the welcome party onward—how she gradually approached and became involved with another man. Knowing she was still a virgin, I was shocked to witness the video of her losing her virginity to another man. This series of events explores profound themes questioning the boundaries between love and betrayal, privacy and ethics.
