Knt stands for Kid n Teenagers. It's a comic. I would tell you all about it but then I would be telling you too much. Just google Knt and go to images and there will be a lot of comics. The Blonde one is Chris. The green haired guy is Ted. And the black haired boy is Aiden. Ted and Chris are 17-18 and Aiden is 12-13.
it's like a comic, i think?
