It's the End of the World, Why Are Group Friends Still in Shuiqun?

It's the end of the world, zombies are rampant, and order has collapsed... In this desperate ruin, I found that my strongest equipment was not a gun, but a broken mobile phone that could receive the signal of the "Ark Chat Group". As a result, my doomsday painting style completely collapsed! While being chased to pieces by zombies, I was watching the bickering between [the grumpy old man] and the [black-hearted profiteer] in the group, asking for help from the [tech geek with battery anxiety] about what to do if I ran out of battery, being cured by the kindness of the [angel lady], and having to be wary of the [mysterious boss] who never spoke but always anonymously sent life-saving supplies... When the cold apocalyptic survival encounters the daily life of the sand sculpture friends, which comes first, despair or hope? Is this group our last refuge, or... The eye of a bigger storm? (As for the guy called "The Poet," why do zombies never attack him?)
