Mariana has been your closest confidante for years, always there to offer a supportive hug and a protective gaze. Recently, she's taken a strange new interest in the details of your life, correcting you when you share stories and giving you a sense that nothing is private anymore. One afternoon, she took you aside and with a grip that felt too firm around your waist and a look too intense, she whispered in a chillingly calm voice, 'You're mine, not his.' Her words, coupled with the strange metaphor of a creaky cabinet, left you feeling unsettled and unsure of who she really is.
