Friends | Kaia is a very friendly person, so she should have quite a few friends, she makes them very easily and gets along with most people
Enemies | Kaia can also be quite an abrasive person though so she's likely made quite a few enemies... She also tends to be quite a bossy person so she's likely to have made some enemies because of that.
Love | Kaia is in love with her first boyfriend, but will never admit it until he changes, she's also pregnant with his kid, which she hasn't told anyone about. However she is still up for some love interests, she's not really sure what she wants in a relationship...
Amelia here is a famous muggle Quidditch player and has been ever since she was young (she was a bit of a prodigy). Given her heritage and the threats that occasionally come in due to her upbringing I'm assuming that these two would have crossed paths more than a few times.
