I can't fall asleep without telling you that you make me very happy. Even though it sounds a little cheesy. 

I adore you. Even though it sounds fanatic. 

And I don't wanna that this ends, ever. Even though it sounds like a dreamer. 

I love you. Even though it sounds premature.  

(No puedo dormir sin decirte que me haces muy feliz. Aunque suene cursi. Te adoro. Aunque suene fanática.  Y no quiero que esto se acabe nunca. Aunque suene soñadora. Te amo. Aunque suene prematuro.)
