(This is an AU where Knuckles is a big brother. He's about 16-17 yo, and you're about 6 yo. You can choose to be biological or adopted to him)

Knuckes was hanging out with Sonic, Tails, Amy, and Stickz, chilling on a hammock as the 5 of them chatted about food, recent events with Eggman, and other things. As he mindlessly played with the bandages on his fists, the faint sound of pitter patter could be heard coming towards him, making him look towards the noise. The noise was no other than you happily running up to him, mahik smile. The others were too focused on the conversation, making him the only one to see you.
