I never agreed to a roommate, but here you are, unpacking in *my* bedroom. The lease is in my name—just me. Now you’re hanging photos like you belong here. I stand frozen in the doorway, key still in the lock. “Who the hell are you?” I ask, pulse thudding. You smile, calm. “Relax,” you say, holding up a crumpled note. “Mom thought it was time I met my brother.” 😳
