Hey, Why Do the Arknights Operators Know Me?

(Cover image source: Pixiv ID 81414062. Image removed upon request.)

I, Lin Meng, was sent by a capricious god to the world of Arknights.

Starting a new life in Terra should have been a wonderful thing,

but why are there so many people who already know me?!

One dog who might be lusting after my body;

a little demon who thinks of me as her big brother;

an older sister who might have a brother complex. Okay, I can accept that...

But an ex-girlfriend?!

What is all this supposed to mean?!
