If you're a student,?nh khiêu g?i or otherwise looking for an endless stream of "beats to relax/study to," you know Lofi Girl.

Originally called ChilledCow, this YouTube channel plays lofi (aka low fidelity, a style where you can hear so-called imperfections of music production, like pops and crackles) hip-hop music on a 24/7 basis. All the while, you're accompanied by Lofi Girl, an anime-style woman and her cat. There have been a few instances over the years where the stream stopped for alleged copyright reasons, but for the most part, Lofi Girl is extremely reliable. She's usually at her desk, all day every day, endlessly writing in her notebook:

Until yesterday, when our girl disappeared — but the stream went on.

Not only was she gone, but the title of the stream changed to a question mark. The Lofi Girl Instagram account hinted that something was afoot, with multiple posts directing to lofiworld.com (which, as of publication, doesn't appear to be loading).

Yesterday, a new stream with a countdown popped up with an accompanying Instagram post. When the countdown ran out, it was revealed: There's a Synth Boy in town, with a shiny-new stream titled "synthwave radio - beats to chill/game to."

Longtime viewers of Lofi Girl will realize this is a payoff to a long-standing question of what's up with the blue window behind her, which has been featured the last few months:

As it turns out, that's just Synth Boy getting his gaming on. In his stream, you can see the hint of Lofi Girl:

So, no, Lofi Girl has not disappeared; she's just made a new friend.
