Surviving high school is hard enough: the impenetrable cliques, strict teachers, scary bullies, embarrassing parents.

Now throw in a city-sweeping zombie outbreak, and cmon!
And phew, it is a lot!
Major spoilers forAll of Us Are Deadseason one follow.

They all end up converging in one place: the classroom.
This is especially true during a zombie outbreak.
Youll need numbers to make barricades, watch your back, and protect you from zombies and bullies.

As someone who hated P.E.
Plus, you never know whom youre going to vibe with.
(Cue the war flashbacks to first semester, senior year.)

Take the wealthy Na-yeon (Squid Games Lee Yoo-mi), for example.
When its revealed Gyeong-su has a scratch, she tries to get him kicked out of the group.
Really, she rubbed Gyeong-sus scratch with infected blood and turned him into a zombie.

When shes condemned by the group, she gets defensive and runs away.
So, if you rewound the moment where Nam-ra slaps her multiple times, we arent mad at it.
(Heres aloopfor easier viewing.)

Avoid Bullies at All Costs
Bullying is, unfortunately, a regular part of high school.
The reason why this tip isnt Stand up to bullies!
is only because of their potential to turn into super-zombies.

Some of the things they teach us might come in handy when we least expect it.
Say, for instance, when your school is overrun by zombies.
Beware of Adults Who Arent Your Parents or Teachers
That isnt to sayalladults are trustworthy.
Adults can be just as cowardly, selfish, and cold as teenagers.
As the students survive, they hold hope that someone is on their way to save them.
When the military sends a helicopter (the second one!)
to the school to retrieve Byeong-chans research, the soldiers are ordered to leave the teen survivors behind.
Accept That Relationships, Like Zombies, Can Evolve
Its normal for relationships to change over time.
Though they were neighbors and friends since kindergarten, Cheong-san admits that he has a crush on On-jo.
Not only can relationships evolve, but so can viruses (umm, sound familiar?
), which turns out to be the case for the zombie virus inAll of Us Are Dead.
Eventually, the virus evolves so that a few who get infected dont show the traditional symptoms.
These half-zombies heightened senses and super-strength consist of Gwi-nam, Nam-ra, and Eun-ji.
Of course, once zombies get involved, everything changes.
And seriously, Mi-jin, its not that big a deal that you didnt get into college.
If the show gets a second season, youll be busy running away from God knows what.
