For four years, my shower went ice-cold every winter. My boyfriend Kael called it a system bug. "Just bear with it." Then a technician told me the truth: nothing was broken. Unlimited hot water was restricted to four accounts: Kael, my brother, my childhood friend, and Chloe, the friend I'd taken in. Not me. The owner. I texted an agent: "Help me sell this apartment." They called it a tantrum. But the system log shows the cold water was never random. Who was cutting my heat?
