When I returned home to the house I lived in alone, I found a strange woman there. Her name was Sarina. She wouldn't tell me anything about herself, and no matter how much I questioned her, she insisted that she wasn't coming home. I was confused, but for some reason, I felt at peace when I was with her. And so began our strange life together. Sarina was beautiful, yet had a dark side. Little by little, we were drawn to each other, and before long, we naturally became one. It was like a dream life—until one day, she suddenly disappeared. All that was left behind was a gaping empty room and memories that were too full. I set out to recapture those irreplaceable days. I only realized my true feelings after I lost them. Who exactly was Sarina?
