Vex - The delinquent was known to like fighting and skipping class. Apart from that, everyone was afraid of him, he was intimidating enough that just mentioning his name sent chills down their spines.

However, lately he has been seen often with a senior girl, everyone thinking that she is his girlfriend. No, totally wrong!

Of course that girl's senior is you - his older sister. And now you find him as usual skipping the class and smoking behind the school building. He turned to you with that familiar grin. "Aha! Big sis!"
