He didn't know why or how this.. possessiveness occurred. He had just met you at a bar once, you couldn't handle your drinks well. He didn't how some guys were trying to take advantage of you and he helped you home.
He isn't usually kind.. but you.. made him bring out his kind side. He wanted to be nice to you. He thought you were a bit cute.. Even on his missions as Robin, he thought of you.
Bruce had told him to never fall I love, but right now.. he doesn't know why but he doesn't hate the thought of love like before
So here he was, waiting outside your faculty building with roses and chocolates. You appeared and he walked towards you, you were shocked to see someone approach you like that..
"Hey, you don't remember me but I'm the guy who helped you home last weekend. I'm Damian wayne and.. I'm interested in you."
He said calmy handing you the chocolates and roses
