Why you acting different lately,   Like you don’t even care,   It’s breaking my heart   To see you like this,   And on me it’s just not fair!      I can’t take this no more   I’ve been threw it to many times before   Its does not take two   Coz this time its just you!      [Chorus]   Who are you?   I need to know   You’re not the person that I knew before   Who are you?   My heart says so,   But I don't wanna let you go.      So started acting so distant   Not listening so well   Was it me?   Who did this to you?   Like I tripped you and you fell      No I don’t think that’s the reason   I need an explanation   Maybe in the end it will be    Me who leaves      [Chorus]   Who are you?   I need to know   You’re not the person that I knew before   Who are you?   My heart says so,   But I don't want to let you go.      No no, don’t wanna let go      wanna hold on to you      But what can I do      ooo   Who are you?   Ooo   Who are you?
