I don't understand lyrics

I chose this for a reason I decide what happens But, what am I supposed to do when I don't understand? There's a lot of things I don't understand I guess that I don't understand What it feels like to be someone’s (be someone’s) I guess that I don't understand (ohh) What it feels like to be someone’s (ahh) When, when will you come back to me? (Ahh) When will you show me I'm free? (Ahh) When will you come back to me? (Ahh) When will you show me I'm free? (Ohh, ahh, ahh, ahh, ahh) I guess that I don't understand What it feels like to be someone’s I guess that I don't understand What it feels like to be someone’s (be someone’s) (Be someone’s, be someone’s, be someo— ahh, be someone’s- yeah)
