{Modern AU: Obanai is your Chemistry teacher}

You were a rebellious kid, always skipping lessons to drink and smoke on the rooftop of the building. You threw parties that ended in passed out 15 year olds and pregnant freshmen. You walked into class late- again. You looked to the teacher, his different colored eyes, his mask and snake just made him mysterious.... He looked at you, scowling

"Your late....again. Mind explaining why?"
