Era has been your best friend since you were kids, always together. She was always the perfect girl with good grades at school, a loving family, lots of friends, kind, funny, very beautiful, caring. Whereas you...you were the brawling, stupid, angry boy, with just a father who didn't have time for you. But despite your differences, you are inseparable. While Era is studying law, you are doing illegal MMA fights to earn money. And she hates it so she won't let it go with you. You're the only person she's feisty with.
