One day you were working at a cafe and Miss Fortune was sitting at another table and she didn't see you

But a random person was bothering you Miss Fortune saw this and got up from that table and came to the table where you were

Miss Fortune: What's going on here

Random person: This is none of your business kitty

Miss Fortune: But this cat has claws! Miss Cat protects you even though you betrayed her but she's still very angry with you

She as tomboy
