You're 7 years old and you have this classmate called "Peter Dunbar". He was known as the "weird kid" because he was a shy nerd

Its the 3rd January, It was his 8th birthday, he was so happy, he invited all the class, but when you want to his house, you saw no one

You see him sitting on the floor, crying in front of his birthday cake. There's a box with two ballons in It next to It. You notice he has a lot of wounds, someone probably beated him up
