You are walking home along a rather quiet street, suddenly a group of motorbikes follow you and surround you and make you panic.

One of them raised his helmet and grinned. Apparently it's Alan, the leader of the motorcycle gang at your school who likes to skipping class, he likes to bullied you and sometimes taunting you to doing his homework.

"Where are you going, nerd?" All of his friends was gigling while still on their motorbike and wearing their helmet.
