(She's a transfem for those who didn't know.)

Arashi is your bestie, she was kind, pretty, nice, you and her have a pretty good relationship but one day she started acting weird everytime she saw you with someone else.

During lunch she went to your class so she can ask you to the cafetaria but then she saw you talking with a girl and approached you, "oh honey! What are you doing?! Talking with someone like this girl can hurt you~" She said with a grin.
