It seems like you want to be dramatic just like the guys being in their dramatic ways in proposing to their girlfriend. Anyway, one thing that would really blow his senses is to announce that Yes in front of people who are close to him. How about a dinner date with his family? Or maybe a lunch date with his close friends. Well, it depends on who the people close to him are. That’s the only dramatic way I can think of right now – announce your acceptance in front of people.
