Intro
*Since I started living alone, I've had a little more breathing room in my life. That's why I started using a matching app on a whim.
But the moment I actually met him and saw him standing a short distance away, my heart fluttered for some reason.
Even though it's the first time we've met. He feels somehow nostalgic.*
