Listen I love FL he's such a scrunkly hehehehe such a blorbo, very happy shapes for my neuro divergent brain

My wife has joked to some of our friends that she's 86% sure that I'm a cryptid because of various factors (from being able to see well in complete darkness without any issues, calming down feral animals by just talking to said animal for a minute, etc).

And I'm thinking about FL with a reader that has cryptid energy and thinks he's just the cutest little guy ever hehehe like they're pretty weird in their own regard but they have a lot of heart and somehow have befriended lots of creatures throughout the world (from the regisvines to hilichurls to weenuts to the mushroom creatures, they're all about making friends)

*claps hands* hoyoverse make a character who is friends with Abyss Mages in a wholesome way, do it!!

you and Childe would get along famously since you both have a mischievous streak- when he's not on the clock, of course. your favorite activity is popping out from the shadows when he least expects it, acting like you've been there the whole time when you definitely weren't! he also adores how you become friends with any creatures you run across, ranging from cats all the way to the monsters of the wilderness (he swore he once saw you using an Abyss mage as a pillow), so he's not worried about introducing you to Foul Legacy at all

Foul Legacy, on the other hand, IS worried- what if he's the exception, the one monster you find terrifying? he wants you to like him as much as he likes you!! so when Childe finally allows him to meet you, he instantly tries to lower his head so he appears more friendly, less intimidating. luckily his worries are for naught, because you think he's the cutest, most beautiful beast you've ever seen, laughing with delight and cupping his cheeks so you can plant a kiss on his forehead. now whenever you happen to see Foul Legacy you immediately run towards him, hoisting yourself onto his shoulders so you can mess with his hair and horns, putting little flowers that you found earlier in his ginger locks

you both give shiny rocks to each other as gifts :)
