Remus Lupin - The Family Man (слэш)

Inspired by my discord server and unhinged I bring you a time travel (Sort of, fix-it) AU that diverts from my original fic Little Star (How I Love You In All The Wrong Ways) at the end of Chapter 31. Parallax of the moon, in which Remus Lupin gets his sleepy, half-thought wish to have done, have been, to be, better (for his loves and for himself) and is somehow thrown fourteen years back in time, into a past that is much like his but also starkly different.
Mourning the loss of a family so recently threatened on all fronts and only just having gotten to a point where they may rebuild stronger, he now must build a new one, which includes finding companionship in Fleamont Potter, adopting the Black brothers, and fighting off the advances of three horny teenagers (the most angelic of which won’t stop calling him Daddy).. But how long can Remus hold on, when he finds his own mind routinely stuck in the future he misses and his body actively drawn to those of the men around him, aged down to boyhood by the years he’s been sent back?
He’s a strong man, sure, but is he strong enough to reject the love he desperately wishes to have, again?
And can he do better, or does better perhaps include indulgence?
