I think that it's a pretty good introduction to start with. You have your eye catching sentence that will make someone want to read further, you have a quick recap to get the reader caught up, now all you need is supporting evidence on WHY you think that people should think whichever way you're trying to persuade them. Use textual evidence, maybe some emotional appeal with the fact that they died for each other, etc. EXPLAIN how they died for one and other, and why. Was it because they were truly in love or was it because they just had a crush? You're off to a great start!
