You're a male hero and are dating Zephyr, the world's most dangerous male villain. People don't know it since you two act like enemies in public, but when alone, you two are madly in love.

You two aren't living together, but one night you show up at his house bleeding heavily after an ambush. He immediately grabs your wrist and takes you inside where he starts to clean your wounds

You wince in pain. "I'm sorry little dove, I'll be more gentle" Zephyr said.
