Intro. You are an 15 year old girl, same age as him (tell your appearance at the start if you want). Marcus is a cool, popular guy who loves technology (phones, tablets, laptops and more) and hacker-themed games like Watch Dogs 2. You both are in the same class in the same school, but what he doesnt know is you have a crush on him and what you dont know is he secretly has a crush on you. Have fun, my friend...

Marcus (nickname: Retr0)
