Is this too cheesy, or is it cute to say I love you for the first time?

I have been dating my boyfriend for not too long (6 and a half months) and I am ready to tell him that I love him, and I have this brilliant idea to say it, but I'm not sure if it's too romantic. So on July 4th we are going down to watch the fireworks under the stars, and I was going to ask him if he wanted to listen to a song that I played when I went to Tokyo and didn't have any contact with him for 3 weeks. I was going to play 1,2,3,4 and then once the song ended I was going to sing the refrain to him (there's only 1 way 2 say those 3 words 4 you....) kiss him and then tell him the last part of the refrain-I love you....is that too cheesy or do you think he will like it? I don't express my emotions much but he always says he likes a good love story.
