Write him a note. And watch him blush. Men in love don't like that mush. They have never been showered with it, except from their mother.
Send him some flowers and just sit back and watch. Watch the way he wonder, just who they are from. Men in love can't comprehend this. From the lady he adore, he's getting this much attention.
Oh, we heard that to get to the heart of a man. It must be in your cooking. But that's just a slogan repeated often.
Kiss him unexpectedly and watch him be shocked. If not amazed that you did it before his friends. Remember many men can't accept surprisingly attention.
But just do it. Just do it. Just do it. All because you love him. What he's going to do except get upset? But he will come around if he loves you too much. So just do it. Just do it. All because you love him.
