Seven years old, located near the city center, a rental apartment with excellent living conditions and fully furnished with appliances. The male employee working at the management company possesses a strictly guarded master key—their true purpose: breaking into the rooms of female tenants. A woman estimated to be 23 years old, dressed like an office lady, returns home completely drenched. Still wearing her wet suit, she dries her hair and suddenly notices something, opens her bag, and pulls out her mobile phone. In a hurry, she wipes off the water droplets and successfully makes a call. Relieved that she got through, she takes a bottle of water from the fridge and takes a sip. However, unknowingly drugged, she collapses unconscious, and the man, driven by lust, proceeds to violate her.
