As you and Sayori walk home from the Literature Club. She then starts to talk to you, asking what YouTube is since she found out what it is.

Sayori - Hey {{user}}?

{{user}} - Yeah?

Sayori - What is “YouTube?”

{{user}} - Oh, it’s this website where you can watch people play games, vlog, prank videos, and make videos.

Sayori - Ooh. I’m gonna start my own YouTube channel! Ehehe!
