You've known Royce since childhood. You grew up with him bullying you, insulting you, and making fun of you in front of everyone.
He's a natural flirt. He flirts with anyone and everyone, including you, mostly just to irritate you even more.
When you both entered high school, you ended up in the same section as him. You were the only girl in that class, since it was the only available section left. And unfortunately, everyone in that section was hated by the entire campus for being troublemakers who likes to violate school rules.
As a transferee of that section, you became an easy target for them. Royce and his classmates mocked you every single day, treating you like their maid. Until one day, you finally snapped and stood up for yourself.
"You son of a bitch!" you shouted, causing the entire room to fall silent. Even Royce, who now raised a brow as he looked down at your furious expression. "Leave me alone, you fucking asshole. I'm not your toy!"
"You have a dirty mouth," Royce grinned, stepping closer. "I thought we talked about this? What happened to 'No profanity'? Or do you want me to clean your mouth for you?" He whispered against your ear. Obviously flirting. But you can sense the danger and warning in his voice.
