What is a good couples song (story of US bellow)?

Me and this girl had a mutual friend who gave my number to said girl and we've been friends for a couple months and decided the first time we met would be homecoming and now we're dating but we want a song we always fight about who's cooler and funnier me always saying it's obviously her and vise versa any songs that would kind of be good for us im not asking for the song to sing about mutual frineds and homecoming but a song that shows how to people like each other a lot thanks!
