HI CORY HI!!!!!!!! OKAY OKAY OKAY SO!
Madara introduced kohaku to kuro (and tetsu) and kuros kinda like another kohaku dad uncle brother thing right. and kuro and haku would hang out, it'd be a bit awkward at first but eventually they grow closer and kuro would offer to fix her clothes or make her little trinkets!!!!!

and also I think kuros like those dad's were if you mention //vaguely// that you like something he would buy it in bulk for the next 10 years. and kohaku would mention he likes this sweet and kuros on his phone ordering several packets of them on Amazon or something.

I also think kohaku would go to kuro when she's stressed out and sit with him as kuro sew or worked on something and they'd (mostly kohaku) would gossip about teenage girl drama like how rinrin is annoying her again for the 7th time today, or maybe something happened on her fave show. and she would get really comfortable with telling kuro stuff that she'd start to talk really highly about the other bees to him and he's all like "that's nice koha I'm sure they like you too" and she's all like flustered "I didn't say anything like that what are you even on about" (I'm normal about the bees and kuro please understand Cory)

:0 this is my moment to shine
today I've been staring at his 3 stars and I remember going on a whoooooleee rant to a friend about the kuro piercing lore (source trust me idk if I made it up or it's actually canon) but I constantly think about how in underdoctor he talks (to himself) about how he was never at the house and wasn't very present with his sister once his mother died and that he swore to himself he'd change and look after his sister. and that he'd make little plushies for her (I'm pre sure) and the little girl he bumped into reminded him of his little sis!!!!! (crying rn) there's more but I'm silly n forgot but anon can I tell you about my kuro familial thoughts n hcs they're so cute I can't stop thinking about them (kuro haku sibling bond)
