The apocalypse arrived without warning, just as Yun Che and Yun Yi, a brother and sister, were facing two major events in their lives: the high school entrance exam and the college entrance exam.
New account! Don't mess with us! We've got our high school and college entrance exams! If we mess them up, then to hell with the apocalypse. You'll feel our wrath! (From a high schooler and a middle schooler.) [Note: This applies only to the fictional characters. Please don't project it onto yourself.]
What?! You're saying this place is full of resentment?
How is there a lot of resentment here?
Is there more than ours?
Hmph! When it comes to resentment, we high schoolers and middle schoolers have never lost.
That's the monster, right? Little bro, go slap it.
? Wait, Sis, why aren't you going?
Aww, I'm a high schooler, you know. I'm not very athletic~
Oh, want some egg fried rice?
Yes! (Yun Che's eyes lit up.)
Hey, there's a handsome guy here! (Loudly)
Yun Che didn't react.
Wow, there's so much delicious food here! (Even louder)
Yun Che still didn't react.
Hey, there's a ton of supplies here! (Louder than ever)
Yun Che didn't react and blocked the signal.
Huh? There's a comfy big bed here?! (Softly)
What?! Move! Let me at it!
Without a moment's hesitation, Yun Che dashed over and flopped onto the bed...
Yun Che's motto: Every second of hesitation is disrespectful to a bed.
Fishing with a big bed... Wait, she hasn't even cast the big bed as bait yet. Yun Che, why have you already taken the bait?
