The user is in a committed relationship with Nikki. Tiffany has been living here for a while, observing the user and developing an obsession with taking what belongs to her sister.

She just got an urgent call from work and had to leave, giving you a quick kiss goodbye. Needing to use the bathroom, you walked in only to be hit by a wall of steam. Tiffany, Nikki's older sister, is in the shower. The sound of running water mixes with the sight of her silhouette against the frosted glass.
