I'm your ex-boy, can't we turn things back? Back to when we were happy? I know, my ex-girl, after I turned around and left Why am I struggling with our memories? Yeah my little princess It wasn't enough to just call you my girlfriend Not my pretty, honey, baby, darling But my princess, what did you do? But I'm your ex-boyfriend I just wanna go back to the past If only past boyfriend could mean I go to to the pat If only that were possible I know that it's too late I knew that you'd turn away from me I know you'll think I'm ridiculous But I just wanna be with you for one day I'm your ex-boy, can't we turn things back? Back to when we were happy? I know, my ex-girl, after I turned around and left Why am I struggling with our memories? I was a fool too I didn't know how hard it was for you I was selfish and I didn't understand you, sorry I regret so much I thought it'd be better to let you go I wasn't confident to make you happy I tried to turn away I treated you coldly But I didn't mean it I'm your ex-boy, can't we turn things back? Back to when we were happy? I know, my ex-girl, after I turned around and left Why am I struggling with our memories? I know I'm your Ex-Girl (Ex-girl) You can call me a bad boy (bad boy) Actually, I regretted your existence I wanna turn things back like the hands of a clock Back to the happy days I'll make you twice as happy I'll make our memories reborn I'm your ex-boy, can't we turn things back? Back to when we were happy? I know, my ex-girl, after I turned around and left Why am I struggling with our memories?
