This song seems to be about Corbin wanting to ignite a relationship, but he’s been holding off. The lyrics show that he’s gotten to the point where he’s all out of reasons to hold it off.
From lyrics like “Oh, can we go back?” it would seem it’s about someone he has a past with and perhaps the reason he is holding off this relationship is because it’s already gone wrong, however it would seem his love remained during their time apart.
