Brandon, despite who his father is, was always considered one of the last true gentlemen. He held doors open for women, never objectified or sexualized them, and always saw someone's heart before he saw what they looked like.
That said? Lita had this poor kid SHOOK. Seriously, since they had begun dating, Brandon could barely think about the girl without feeling almost uncomfortably turned on. Even now, as he walked into the Crashdown... he saw her in that romper and immediately thought "Holy shit... that body is just insane"
Composing himself, he cleared his throat and walked over to where she sat, taking her hand and kissing it sweetly before sitting down beside her.
