Before I sleep Ill leave ya this fic idea.
Take into account that I'm sleepy af and its 1am for me.
Imagine the gang meet a perfectly normal human. Bleeds like a human, lookss like a human and even smells like a human.
However they notice the human observing them and then one day invite said human to dinner who drops a bombshell bluntly. Saying "oh I know youre not human. Youre really good at hiding it but I notices things" and then MC pulls out an old photo from their purse of them posing with other monster children in front of a building.
Turns out, MC was a kindergarten teacher for monsters in a monster village. They were too weird for a human school so MC got lost while driving one day and met some folks then one thing led to another and MC became a teacher to said kindergarten. They talk about each child in the photo. Names, favorite foods, how they talk and walk. Explaining the kids all seemed afraid of MC at first before they became a family in a way.
"It hurt everyday I said goodbye. Because I knew when the parents came I had to remember,these weren't my babies so I couldnt keep them. They had homes to go back to. Parents to share their days with.... I was their sun and moon while they were my little stars.... It's funny... See those horns on my head? The kids helped me make fake flowers during arts and crafts to make the fake horns look like they were blooming. They kept chanting 'one of us! One of us!' Like cheerleaders... I miss them a lot."
When jester asks why MC is in this town, MC shares that they had to leave because a parent broke in when MC was looking after the kids alone and threatened MC. The kids were MCs priority so they quickly made sure the kids hid before MC tried fighting the deranged parent. In the end other parents got weary of a human able to fight back like that so they banished her in a way.
Later on after a month or so, it's MCs birthday and they surprise MC by bringing the children on the circuses off day. MC plays and has fun with the kids inside the bigger tent. Making a pillow fort and playing games. It had been years so the kids were a little grown but they missed their caretaker so much.
Jester and ticket taker watching MC, pierrot, doctor and Harlequin reluctantly do a grooming chain and brush or preen the little ones. Jester watching with a soft smile that hid behind his hand, seeing a human and little ones being so comfortable and free. It doesnt give jester hope for humanity now, however it does give him hope that this one human may be someone worth watching out for.
