In the dimly lit room, a brother and sister share a cigarette, the ember glowing in the darkness. The intimate act sparks an unspoken tension between them. The sister, her eyes heavy-lidded, takes a deep drag, the end of the cigarette illuminating her face. She passes it to her brother, their fingers brushing. He takes a long drag, his gaze locked onto her. The room is filled with the scent of smoke and something else, something heavier, more intimate.
