My childhood friend and I were very close and meant the world to me at school. However, I've been suffering every day because of a bully who transferred into our new class. When my childhood friend tried to protect me and scolded the bully, he suddenly demanded a ridiculous condition: "I'll stop bullying you if she dates me for one week." To protect me, my childhood friend agrees to date the bully for seven days—leading to an intense situation where they continue having sex. I secretly watch them, tormented by guilt, yet strangely aroused. But watching isn't enough for me anymore.
