The apartment felt suffocating, even with the air conditioning on full blast. A text from Mark, her supposed boyfriend, buzzed on her phone: *Running late, babe! Stuck at the office.* She sighed, the sound lost in the drumming of the storm. It was always the office. Another Friday night, alone. A new message popped up, this one from a name she didn’t recognize: *Hey, is Mark with you?*
