Easy as Falling by Viano Oniomoh

His sole job as a Guardian is to guide his charge to the best of his ability. If he’s seeing glimpses of a life where he seems to have formed a lovely relationship with his charge, it must be some kind of mistake.

Jack knows there’s something wrong with Michael. For some reason, it seems his guardian angel doesn’t remember who he is. Then again, Michael has been breaking all of heaven’s rules for years now; this had to be him finally paying the price.

Jack doesn’t want to lose his angel, but he doesn’t know what to do, and while the Guardian can’t remember, he can’t seem to shake off this strange ache of something missing.

As it turns out, when it comes to matters of the heart, there's not a power in heaven or on earth that can interfere.
