[6] It sees Green "lamenting over a failed relationship" while he sings about his "shortcomings as a potential partner", particularly "that he grows attached too quickly".

[7] The music video "delves into the puppy-love stages of a relationship in elementary school and grows into adulthood when the couple deals with life’s hurdles".
