Since my post on my potential Deltarune AU has been doing well, might as well post the only two references I did for the time being. (More will come soon.)
As for the AU...it's called Moonlight Mischief.
Its an AU where Darkners and Lightner humans/monsters co-exist (like Monster Musume where fantasy creatures blend into society.)
It focuses on Erin and Tenna, but the other Deltarune characters will appear as well.
Erin before meeting Tenna was a librarian who still lived with her adopted mom.
Big fan of Tenna's show TV Time, and watched it a lot.
Way later, she meets him in person (probably due to some sorta event where he talks to fans.) and the two eventually hit it off.
They start dating to the point where Tenna offers Erin to work with him, making her ditch her former occupation.
Once that happens, few days after they date, Erin somehow starts shrinking when the moonlight's strong.
It happens randomly out of the blue which scares her, but then she realizes that she can use that to her advantage.
(Also Tenna lives in those really rich apartments so its very pretty and nice in there)
Erin loves to run around while being mouse sized at night, listening to her beloved snore, as well as pull mischievious pranks as he sleeps~
A bit later in the story, the two marry, and live in a mansion.
That's where i'll introduce the other characters, as during the arc when the two are dating, only the tv time characters are present, with the Fun Gang showing up here and there when Erin and Tenna are doing things on their days off.
It will be a comic series that I'll hopefully start on soon. I've been wanting to do a slice of life AU for a long time.
Keep an eye out for more!
