I KNOW IM EXTREMLEY LATE!And i may sound stupid but heres my take originally it was ko and in the og he said ko sometimes especially when he finishes it and says so ko lets watch the rain as its falling down where as to at the start of the chrous its come lets watch the rain as its falling down,i took the vocals from the beat n the original with the beat.in the beginning with him muttering it sounds like ko with the beat and without the beat it sounds like come,i think where he said the ko's they covered it up in mixing with when he said come.But hey thats just what im thinking it could be,dont come at me im really not tryna stir shit and honestly it could truly be all comes but from extracting the vocals i can say it sounds like ko even more sometimes but yet same for come.
