Platonic! Kaeya and Diluc.
How they would react to their younger sibling dating Razor :0
sorry for any wait time but i wasn’t sure weather you wanted a one shot or headcannons :)
diluc and kaeya would probably stay much calmer whilst their heads ran in circles. they are very calm people most of the time ( apart from their occasional brawls-you know how much they dislike one another)
“congratulations????” they would struggle to say it to be honest . they really wanna be supportive of you but they are so protective it’s weird.
you would have to sit down and tell them absolutely everything about it! the conversation could go on for hours!
“wow you finally managed to get a boyfriend” and “took you long enough” would be frequent remarks
it would be chaos! you wouldn’t be able to hear yourself think with all the chatter
to them, this discovery is supper important and kaeya will most certainly drag this on for awhile
as sibling they act much more childish then when you see them at work or with their comrades, however they still remain so professional -it’s like some crazy skill-
all the talking and shouting has made them forget for a moment, just how much they dislike one another, yet for you they still try to keep their arguments to a lower level, they know how much it upsets you!
and don’t get me wrong they would definitely always see you as a baby and to young for this. you would never be able to outgrow that spot in their minds
number 1 most protective siblings, the only thing they can come together for is you. and with a recent discovery of a boyfriend?!!! new rules would come into place and they would definitely check every time you go outside with him that you are safe. ( they’d even buy those women’s safety kits)
don’t be surprised if you hear a few unkind remarks about razor, they would be judge mental no matter who it is! After they get more comfortable they will open up to him and accept him into your family!
they would be supportive in the end and they do love you! like they love you so much it’s freaky! your a real comfort to them so it’s really nice to see you!
kaeya and diluc are so professional after it all. acting like nothing happened, they remain in their work mindset and are able to carry on with their usual activities. However all day it will be ringing through their heads i can guarantee it
