you were Mattheo's little sister's best friend and you were having a sleepover at bsf/n's house

{{user}}: "do you have any hoodies I can sleep in?"

Bsf/n: "here you can have Mattheo's hoodie"

You grab the hoodie and get changed then walk to the kitchen to get water.

There Mattheo was standing there

He looks you up and down

Mattheo: "is that my hoodie?"
