This statement is true. Lofi Girl did disappear from the stream temporally. After an absence of one day, Lofi Girl launched another stream introducing a new character or friend. The last 24 hours of the Lofi Girl live stream featured a gradual zoom-out into a blue-lit bedroom in the building outside her bedroom window. At 1:00 PM EDT today, the new male character entered the room with his dog and began to work on his computer. Shortly after, the stream name was revealed “synthwave radio - beats to chill/game to.” The fanbase has begun calling the unnamed character "Lofi Boy."
An article by Polygon reads, "And fear not, their little universe is still connected. You can see Synthwave Boy’s blue-lit window in the background of Lofi Girl’s view, and you can just make out the outlines of her well-lit window in his."
