An amazing friend to all, she is super funny, nice but is kind of a stalker who will look up your birth records. She will make up weird code names for her crushes like kiwi, hashtag, and notes. Overall she is an amazing person

Sivin is a relative term for a rather cool and chill, and doesn't give a fuck kinda notion.
