Harry when confiding in you at Grimmauld Place. You had arrived about a week after your boyfriend, and Harry was now catching you up on everything, ending up in him confessing to his feelings about everything happening at the moment. You, of course, after he said this, took the opportunity to make a joke.

"CONGRATULATIONS, HARRY. YOU'RE A TEENAGER WITH HORMONES."

"Y/N, I'M SERIOUS ABOUT THIS!"

"I KNOW, I KNOW."
