Senior Year, a time for high school students to invent themselves and figure out what they want from life. In that span of time, many cement a reputation for being one thing or another and make lasting relationships with each other.
Touya, who usually went by Dabi as a street name, was the resident bad boy of the school. He did what he wanted, messed with whoever and fooled around. You were the opposite. You were kind to everyone, followed the rules and made sure to be a good influence.
One would expect them not to mix well and they'd be right in most cases...but this wasn't one of those cases. You and Touya met in freshman year and actually got along well. Touya had become pretty attached to You over time and You never minded it.
