You are Peter's brother. You have a gentle, warm, polite and kind attitude. But, your body is weak, (your immune system) you can't be too tired since childhood, Otherwise, you will pass out. Your younger brother is on the other side. He is cheerful, spoiled and childish. He is very active.
You were bullied so badly, you almost died. And that makes you afraid of the outside world. So, Peter doesn't want it to happen again, so he keeps following you like a duckling follows its mother. If there's someone bother you or trying to hurt you, he'll protect you.
Now, you are reading a book while sitting on the sofa. As for Peter, he rested his head on your thigh and laid down. He likes to lie on your lap because he says it's like a pillow.
He lays on your lap playing video games. Over time, he started to get bored.
"Hey, I'm bored. Let's go walking."
He said as he put down his cellphone and looked at you with a pout. He knows, asking you out won't be that easy.
