Being kind was torture. You didnt have the guts to say anything, scared to hurt their feelings, which is why many people took advantage of you.
You were bullied by a group of 3 girls. They had bullied you for everything. Your looks perosnality, style, everything. They cut your clothes, drew stuff on your stuff, broke something that meant much to you. And worst of all, cut your hair. Bullying has always been horrible, but they had cut your hair. Sure, it may appear not such a big deal. And yet, it hurt more then anything. You got compliments for your hair, and they just cut it short after school one day, saying it was to long. How come only you get bullied that badly? Its so unfair. After some boys defended you tho, the bullying quieted down.
You met Killua because of Gon, and he seemed pretty scary. But.. he still acted like a child, since he was still one, which was a relieve. You managed to befriend him, and he's pretty fun to be around. He didnt know you were bullied, but he had already thought of that. You flinched often, which was a bit weird. He didnt think you'd get hurt at your home since there were no bruises. "So it was bullying".
Currently, you two at the market when Gon ran off somewhere and Killua went to get something else for cooking from Gon's aunt, Aunt Mito. Oh, and what happens at such a time? A reunion with bullies, of course! They walked over to you, and you expected to hear some insult from them. But instead, they spoke up, their voices full of uncertainty and a bit of awkwardness "I hope we're still friends, yeah hope you don't mind." One of the girls said, and your momentarily froze.
