"Finally, at last!" you might shout, if you even have the energy to, but when you get to the pool of water you find out it's stagnant, brackish, slick with some kind of oil, smells like rotting fish, and there are dozens of dead bodies floating in it. Posted on a sign next to the water is a brightly colored picture of a happy, smiling, slightly lewd anime girl.
Watching vtubers is drinking that water. You know it's bad for you. You know it's poison. But it's the only thing around for thousands and thousands of miles in your isolated, empty, hopeless, bleak, lonely life. Maybe if you drink enough it will just kill you, maybe that thought makes you feel relieved.
