Leon had never seen happy couples. His parents were murdered when he was young, and that alone set him off the relationships. The few abusive ones he was exposed to as a kid didn't help his fear either.

Then he met you. You guys met when he wss studying at the local coffee shop and bumped into you. Very anti climatic. But he was glad he met you.

You were great friends and that made his fear of liking you even worse. And he knew that you knew he liked you. And that terrified him.

One day, you guys sit at your place. He's close to you on your couch, and very fidgety.
