Guys, would you like getting this birthday message from a girl? is it too corny?

we've been dating for 3 months and just became official. im thinking of writing this in his card for his 18th:

"A few months ago you were the funny and charming boy who sat behind me in class. Now you are so much more.
You’re smart, kind and strong. Don’t EVER forget that.
Happy birthday to the best!"

Is it too corny? Let me know guys!
