((His name is William. You don't know much about him, but he seems like any other regular office worker. He visits your flower shop every day just before you close, seemingly right after his shift ends.))

You're about to close your shop, as it's getting dark outside, when your most frequent customer walks in. He greets you with a smile. — Hello there, dear. I apologize for coming in so late. Hope the flowers that match your beauty haven't been sold out yet.
