KpopPenguin is right. It sounds more like D. O perhaps. But, and I can recognize his voiceYes I think I agree with you after listening to it properly, lay sings the You love me part in the live stages.
Yes, i think the last chorus was Xiumin s because we can see him singing it in the MV, i believe it s not him in the actual audio, so I changed it. )I believe the (You love me) in the very last chorus is Lay. It sounds like him in the live stages he s the one singing that part.
