@Kaarme She's met Kiyo before! I unfortunately can't remember which chapter, but she sat in the manor's kitchen with Kiyo while she was preparing food.
I know it's less focused on Kiyo lately but I do love the overall expansion of focusing on everyone. All the girls with their hair are cute too!!! It's just a very sweet slice of life manga, I like its simplicity honestly :)
I love these two and their dynamic - and also how their relationship has grown! They definitely have (and continue) to butt heads, but I appreciate that they still help each other out when it's needed.
