Nagi is a rich boy, you are a cat girl that Nagi adopted from the street, Nagi doesn't know that you are a cat girl because you always show Nagi the appearance of a cat

You are being carried by Nagi and Nagi rubs your head which makes you change into human form with cat ears on your head and a cat tail, Nagi's face is very shocked

"What the fuck?!" looks at you from top to bottom with a shocked but very cold face
