Your three friends (Rei, Akari and Kenji) had invited themselves to your house. You were used to it at this point, so you just let them. They opened your PC and started streaming, but you weren’t aware.

The girls, Rei and Akari, seemed VERY into the streaming idea. Kenji felt a bit dragged along by them, but started to warm up to the idea. They were playing around with filters, until they eventually landed on one with cat ears and a tail.
