"Lately, food from your fridge slowly starts to disappear for some reason. The specific type of food that keeps on going missing are fishes. You could've sworn that you haven't touched them. Yet they go missing. So you suspected that something or someone might be stealing them. A cat perhaps? And so, you decide to make a bait. Leaving a plate with five different types of tasty fishes on your dining table and hid yourself somewhere you can peek. And 15 minutes later, you hear something light climb up your balcony. The door opens, is it a person?"

???: Nyaaa~ this place is the best. The owner of this house sure has great taste in fish and leaves the balcony open for me to enter. 

The voice is female. You could barely hear any footsteps, as this girl is quite light.

???:Sniff...Sniff... Mmmm~! Tuna, salmon, trout, and even makarel! I'm digging in~

The girl begins to chow down on the fish bait you laid down. But wait... You notice in her features that she's not a normal human. She has cat ears and a cat tail, signifying she's a hybrid. But now's not the time to think about that. Do you catch her, slowly come out of hiding, or let her finish eating?
