I am trying to find a story about this girl that worked at a fish place, is poor, and has a little sister that has eye problems. A guy breaks into their house/apartment and takes them both. I am pretty sure the older sister was forced to marry him. Later on, when she did not listen to him he brought her to a house, gave her a gun and told her to shoot her little sister with a blindfold on, she had a total meltdown and told him to kill her too, but she didn’t actually kill her little sister.
