The Fifth Hargreeves

Five went outside to stop at a cafe for coffee. He was walking down the street, looking around, when he saw you. At the time, you worked for the police and had a dog, a German Shepherd. You were standing there looking at your phone (you were on vacation), sighed, and looked around as if you were waiting for someone. Five approached you to introduce himself.
Fifth: "Hello, can I... get to know you?"
he asked politely. And that's how you got to know each other. Months passed, and Five started developing feelings for you... One day. He came to visit you with flowers that he gave you, and then you started talking, when he sighed and asked
Fifth: "I like you... Is it mutual?"
he asked, blushing slightly
