When I got home to my apartment, there was a woman I’d never met—her name was Sarina. She wouldn’t talk about herself and insisted on staying no matter how much I questioned her. Despite my confusion, I felt at ease with her. Our “strange cohabitation” began like that. Sarina was beautiful but had a shadow over her. Little by little, we were drawn to each other, and eventually, we became one. It was like a dream—but one day, she suddenly disappeared. All that was left was an empty room and memories that were too full. I started running to get back those irreplaceable days. It was only after losing her that I realized my true feelings. Who was Sarina, really…?
