She is mine.

You have no right to touch her.

♪I am lost in the dizzy pull of your fierce attraction♪

♪So devoted that I would let this obsession last until the end of my life♪

♪Will your love ever burn as fiercely as mine♪

[Affinity]

♪I'm a slave to you♪

♪Can you feel that you're my fire?♪

The person who hurt you is under our control.

You are safe here.

The one who attacked me earlier

looked just like that silent teacher we saw today.

He came back to life!

Did you get hurt trying to protect me?

I'm sorry.

I...

I administered a high-dose sedative to him.

I did not engage him directly.

I also notified the Security to deal with it.

And one more thing.

Pulling little stunts on me.

Do not do that again.

What a nightmare.

Does Genus lose power often?

This is not

a routine outage.

Why is there still no signal?

It must have been cut as well.

Assistant Li.

Assistant Li?

Has an emergency occurred?

Twenty minutes ago, she was attacked by an unknown man.

And

that man

was very likely a body donation volunteer.

That is impossible.

They were already...

Could it be that

someone used an unknown method

to control the donor's body?

I will consult with Security.

The director is in the morgue on B1.

Go brief him on the situation.

[Genus]

[Morgue]

There should have been over a hundred bodies here.

Mr. Ding.

[Morgue]

Mr. Ding.

Were you attacked by the silent teacher as well?

You were attacked by them?

One of them has already been restrained.

Assistant Li has gone to alert Security.

What about the bodies inside?

At first, two bodies suddenly went missing.

So I came to check what was going on.

Then they left.

Luckily, I reacted fast.

Otherwise I wouldn't be standing here telling you this.

[Yi Hang. Affinity B]

This belongs to an Affinity B infected individual.

You are not running secret experiments

on these infected ones, are you?

And things got out of hand?

Her internship at Genus

is covered by a strict confidentiality agreement.

Five years ago,

Affinity B carriers were involved

in berserk attack incidents, for the first time.

That led to the establishment of the Special Administration Bureau,

to place them under control.

At the same time, research began on the virus within them.

The conclusion was that

Affinity B

greatly enhances the physical potential of carriers,

granting them extraordinary destructive power.

And then,

the government later named this group "Ren".

[Ren (Blade)]

Affinity also caused a small number of Ren

to develop emotional deficiency.

In other words,

they cannot feel

or truly understand

emotions like love, or pain, unlike normal people.

That is one way to put it.

So,

they're much more likely to turn antisocial

compared to regular people.

Just like they said on the news.

They will turn crazy

and become antisocial.

Just look at this.

Those were his own parents...

Later on, the government saw their value.

Using them

to carry out dangerous missions

to protect ordinary people.

But Ren,

once a mission is over,

are prone to losing control and hurting others.

When they

become overly excited,

their virus load

will...

Will surge.

Then they lose control,

lashing out uncontrollably.

In the end,

they would burn out.

Some didn't survive.

That kind of loss of control

can be addressed.

Under certain conditions,

Affinity A

can suppress Affinity B.

Simply put,

that means

an Affinity A carrier

can guide a berserk Ren back to normal.

However,

the two must be of opposite sexes.

So, later on,

this group was named "Yin".

[Yin (Guide)] They naturally attract Ren.

So how does a Ren

identify an Yin among crowd?

Yin,

under the virus's influence,

have blood,

tears, and other body fluids

with a distinctive scent.

Ren have extremely keen senses.

They can detect it.

So how can an Yin guide a Ren back to normal?

Through deep interaction of body fluids.

We call it

"forming a pact".

A common and relatively safe way to form a pact

is for two people to get married.

And through the

marital intimacy...

Now, many Ren have already

return to normal life

by marrying Yin.

So a pact

is essentially marriage.

No.

It is even stronger

than an ordinary marriage.

This is a one-to-one bond, permanent and exclusive.

After a pact is formed,

the virus develops exclusivity.

From that point on,

this Ren

can only be soothed by this Yin.

And this Yin's bodily fluids

no longer work on any other Ren.

They

recognize only each other.

However,

there are far fewer Yin than Ren.

That is why Genus has spent years

researching inhibitors,

to deal with the problem of Ren losing control.

So they developed it?

So Mr. Gu

saved me just now using the inhibitor, right?

Inhibitors work by lowering viral activity,

forcing Ren out of an overexcited state.

But it won't last.

Resistance increases with repeated use.

Eventually, the inhibitor stops working.

That is why

we need to keep improving the inhibitors.

In fact, these Ren came here today

as volunteers to test the new drug.

No one expected them to die after testing the new drug.

Could the side effects of the new drug

be something like

temporary respiratory arrest,

and then

they were mistakenly declared dead?

Go to Security.

It is safer there.

Let me tell you something amusing.

Those Ren

may look intimidating,

but every time they go through drug trials,

they scream uncontrollably, like a panicked animal.

Just thinking about it makes me laugh.

They were like fools.

You sound so entertained.

I want to hear it too.

- Come on. - Come.

Just thinking about it cracks me up.

Give me a throat lozenge.

I have something even funnier to tell you.

Here.

Sheng, your story makes me feel like

[Nan Xing. Affinity-B] having a bowl of offal porridge tonight.

Here.

No.

No.

No.

Try not to scream like an animal.

Hi.

You are still alive!

Oh.

Just consider this as an innocuous joke.

But next,

I am getting serious.

The hunting game

officially begins.

I heard gunshots over here.

I saw someone running that way.

Nan Xing.

The inhibitors

are all secured.

Nice.

Hand them out later.

So we do not lose control and hurt our own.

Let me think.

Next,

how should we play with these little rats?

Should we

leave survivors?

If we find an Yin, keep them.

In the future,

this place will only be full of

free,

happy, and united

Ren and Yin.

It must have been those Ren.

Check the cameras.

They...

They are not heading for the dorms, are they?

Hurry, find the elevator keys.

Stop them.

Move, now.

What did you do to those Ren?

Why are they trying to wipe everyone out?

It really was just a standard drug trial.

We...

They even signed Informed Consent Forms

and Body Donation Agreements.

The keys!

What are you messing with behind those screens?

It is useless.

Looks like some little rats

are secretly watching us.
