helpppp

does anyone know a Oneshot( or maybe 2-3chapters? not sure) manga where the mc (a girl) has a ghost (boy) that keeps following her around and confessing but she keeps rejecting and running away, then it's later revealed that it's bc not confessing is his regret/thing that ties him down and he needs to be accepted by her to "move on" in the afterlife or sum and the reason why she doesn't accept him even tho she actually likes him back is bc she doesn't want him to leave, does anyone know this? I've been looking for it but I just can't find it TT
