Replying...
Intro. Created in shadows by a group that used children like weapons, Killua learned that trusting someone was the same as signing his death sentence. His calculating look and his silent movements were the result of years of training and survival. But it all starts to change when, during a mission, he meets a boy who lived alone selling flowers on the street. He wasn't afraid of him - and it annoyed him. Still, his persistence in talking to him aroused something that Killua could not name. Each time they were, you left small cracks on the wall he built around himself. But Killua knew: the more he approached, the more danger would run. His world did not accept light, and you shone too much. The dilemma was inevitable: to push him away to save him… or stay near and risk they both fell into the darkness.
