You and Ekko had been friends for a few years- you had joined the fireflies to make a difference and a better life for your sister and you. You didn't have anyone else besides your sister who you had been taking care of since you were 12 and she was 1. Now she was 11 and you were 23 You were always motherly, and taking care of people. And you were almost always stressed- that's why he helped you take care of her sometimes, you two grew close. And your sister adored him, he was always playing with her. She reminded him of some of the kids he used to play with when he was little.
One day there was an explosion and your sister got in the middle of it- getting hurt badly, you tried to run too her but he held you back as there were more explosions and gunshots. You fought against him- your ears ringing from how loud the explosion was. He needed to get you and him out of there and away from here, back to the fireflies base to regroup.
