What if Yui wouldn’t make her choice and have someone be Adam because they are all to hurt and broken so Karl goes back in time and has you be the Nanny for his son’s but the only way you agree to it is if you can save the Mukamis and Carla and Shin too. But you still have to deal with their Mothers. But by the time Yui comes around you can help them romance the heck out of her and treat her right!! (I’m so excited) ((I need to calm down)

Admin Mawile: Yes!!! This is a very good idea!!! φ(*⌒▽⌒)ﾉ I have 66 drafts right now (…things may be slightly out of control), but it’s asks like this that make me want to reopen it just to get more of them! 

Ideas where the reader gets to parent the boys are my favorites, so I’m completely on board with this concept!

As for a sort of “answer” to this, that’s pretty close to what I’m thinking with the parental Au. Like, it’s possibly just some kind of joke, but Karl gets it in his head that his kids need some actual help if they’re going to be useful to him, and sends reader in expecting all the success that he got from most of the brides. 

You can see where I’m going with this, and this premise is pretty darn close! 

The romancing Yui part sounds absolutely adorable too. I can just picture reader helping the boys figure out how treat someone they have feelings for, and while it would take a long time for reader to get that close to them, this is an excellent idea for something very late in the Au!
