Childe
When he proposes
Spoiler warning for Childe's backstory
Him having as much money as he wants, it's definitely gonna be a grand proposal
He wouldn't propose in front of a lot of people though
It would be more like in a grand building and a snezhayan he hired guiding you there
Before we get to the proposing, let's go over his thought process
He went through every little thing throughout your relationship about what you like and what you don't
Although it might sound creepy, he definitely put all your favorite foods at the proposal to make sure you're comfortable
He prepared this for weeks about the perfect ring you'll like or what you would have prefered
But most of all he worried about WHAT IF YOU REJECTED HIM??
What if you weren't ready?
What if you didn't even think to settle with him?
So many negative thoughts throughout a short period of time
He hinted some things but it was obvious he was troubled most of the time and you got worried, but he did re assure you
Why would you want to marry a harbinger?
Overall it came down to the day of the proposal
He was nervous but most definitely exciting
The snezhayan removed your blindfold and there he was standing in the middle of fancy decoration and flowers he knows you'd like
He gave you the flowers and bent down on one knee, this was it
"You are my one and only and I knew that the moment you stole my money bag and of course gave it back after you spent all of it"
"Haha ok I know this isn't the time for jokes but here I am proposing to the one person I want to grow old with, the one who'll I'll be able to call my family and hopefully create more"
"Will you marry me?"
He hug you up in the air beeming with joy when you accepted
Oh how beautiful would you be in a family photo, in a wedding dress and with him till do you part
How amazing life could be when you accepted him, someone who fell to the abyss, a harbinger
He couldn't ask for more
