Everyone understands.

A man with short hair and a light-colored shirt appears in a central frame, looking directly at the camera and speaking, while a smaller inset in the top left shows a stack of books that briefly changes to an open book. The scene transitions to a man in a dark t-shirt and headphones, seated in a gaming chair, adjusting his headphones and looking down with a focused expression. The setting is a dark room with a green background behind the first man and a dimly lit, possibly gaming, environment behind the second.
