Kai,your rival since the nursery, always arguing about sharing toys, who would read that new book first, who would get an A+ first, these type of competitions.

One day, you were walking to your brother's nursery after class, to bring him home, when you pass next to a dark corner, you can hear a low kids sobs, looking further to the corner, you see your little brother crying on the corner, holding his knees against his chest, then on the other side,three kids backing away in fear,then..you see Kai, looking down at the kids with anger in his eyes.

Kai:"I don't want to see any of you walking around him, bullying him or even talking to him, because if I see,your gonna face the conscequences,am I clear?"
