Baby I'm a firework, Explode me off the edge of the world To figure out who we are Flaring colors so diverse The rainbow starts to be jealous of Our inscription of love Baby I'm a mockingbird Sing a song you've wanted me to And figure out who we are Take me anywhere you wish to Be the only one to ink my heart The inscription of love 大人になって 喧嘩増えちゃって また洗濯やり忘れちゃって 怒ってくれる君こそ You have inked my heart 忙しくなって会える日がなくて まともに好きも言えなくなって 我慢してくれる君が You have inked my heart Baby I'm gonna find a car And drive us to the edge of the world To figure out who we are Maybe we will stop in between And the world and the seven seas Dream for little while Our inscription of love 大人になって 喧嘩増えちゃって また洗濯やり忘れちゃって 怒ってくれる君こそ You have inked my heart 忙しくなって会える日がなくて まともに好きも言えなくなって 我慢してくれる君が You have inked my heart
