Dark
Sakura loved the dark. To her it meant the end of a draining shift and the warmth of her lovers arms. It meant that she could relax, in the dark she could remove herself from the trials and tribulations of the hospital. Every light in her house was on a dimmer switch, providing just enough light to find her lover sprawled on the couch as he waited up for her, just enough light for her to look up into his dark eyes and remember who she is, to forget about her work.
In the bright lights of the hospital, Sakura would lose herself, falling deep into her work, trying to shield herself from becoming to involved with her patients. But she always ended up knowing every one of them, and that made the pain worse when she lost them (made the joy better when she saved them, said a voice in her head). True the bright lights brought her pain, but nothing, nothing, could compare to the joy of saving a patient others had given up on.
But still, Sakura loved the dark. It was safe. To her it signified home.
