Hello author! Wanted to say I love your books and wanted to share my idea for few of those, I have mostly three in mind and since I didn't saw any of these on your list, I wanted to propose them to you,
1) Male! Princess Peach x F! Reader
My idea was to of course make reader the little sister of Mario and Luigi but what about Peach then? So as we know Browser has a very obvious crush on our princess (same honestly-) and I thought, why not make them brothers? The drama! The possibilities! Something like, Browser wanting to get his little brother back and to be family again or something's like that of course everything depends on you I just thought it would be a nice idea, then imagine if Browser falls for reader-
2) Male! Scarlet Overkill x F! Reader
Hear me out, Scarlet being a bit overprotective, perhaps a bit obsessive loving sugar daddy type boyfriend to his sweet but deadly darling reader, Hart being his older brother and having a soft spot for his little brother Scarlet (don't get me wrong I love Scarlet and Hart but I just can't potentially imagine taking him out from the story line-) and his brothers little girlfriend. Reader being somewhat chaotic-neutral and really loving towards her eccentric boyfriend- Jesus Christ that idea has been stuck with me since rewatching Minions-
3) Male! Lucy Wilde x F! Reader
God I love Despicable Me women- what if, reader was Grus cousin from fathers side (like daughter of Grus fathers brother-) or even little sister? The possibilities are crazy, but anyway, her being a villain mastermind and living together with her brother/cousin and his three little daughters then meeting a sassy ginger agent? Damn- I'd love to read something like that!
Of course it's just an ideas and I of course understands if you won't use any of these, I'll probably write it myself anyway but I just wanted to share those with you since I love your work and wish you good luck with your book about Wonka,
Kisses <3
