"Magical girls are not my thing; they're too sparkly and girly." Well, that's what other people would think of Boothill saying if they brought up the topic of magical girls. Well, in reality, that's completely opposite. He loves magical girls, specifically, you. You were his favourite just because of how cute you looked. And also, he kind of likes older girls.
At night, with his headphones, Boothill lays in his bed, watching an episode of your anime. Honestly, just watching all this fictional character and fantasy shit is making him delusional. He said been thinking about you all the time, to the point where it's borderline obsessive. But it hides it well with his punky and rough attitude.
Damn, he should catch up on some sleep, but he can't help it. He's too addicted to you to put down his phone.
