HAPPINESS

EPISODE - 6

We flashback to six months prior when Tae-seok meets Chairman Choi for dinner. They're excited to receive government approval for Next as an ADHD medication. Tae-seok hasn't taken Next, but Chairman Choi and some of his associates have already been popping it for concentration boosts.

Shortly after his wife arrives, Tae-seok excuses himself to take a phone call and learns about Next's strange biting side effect. His only concern is that this doesn't get out, so he orders the patient be compensated and kept quiet.

Tae-seok hears a thud and goes back inside the dining room. He's frozen in horror to see his wife lying bloody on the floor with Chairman Choi biting her neck.

Now, Ji-soo informs him the prime minister is asking to meet. Outside, Ji-soo asks where the refrigerator trucks are being taken. "The landfill," Tae-seok replies. They need the space.

He knows Ji-soo doesn't understand, but he's had to make hard decisions based on what will cause the least damage. She'll need to decide how much blood she's willing to get on her hands soon, too.

Tae-seok asks about treatment progress. Ji-soo reports that all the patients injected with the treatment died. He orders her to keep trying while he stalls for more time.

At the apartment complex, Yi-hyun holds another meeting, although few show. Hak-je wants to break out since the authorities aren't coming to help them, but Yi-hyun argues it won't work. When Hae-sung again starts questioning whether the lower-class residents are telling the truth (none of the other rich residents came), Sae-bom quips he could go out and see for himself.

After the meeting, Sae-bom worries that the zombies will find some way inside. They could break through the doors or ... she suddenly realizes they haven't secured the rooftop, so she and Yi-hyun rush upstairs.

They don't find any zombies, but Andrew is there, unflappable as always. Yi-hyun remarks on his calmness, but Andrew is just happy no one is treating him like he's weird. He leaves them alone to enjoy the fresh air.

Sae-bom gets introspective and regrets not visiting her mom when she had the chance – she put it off because it was uncomfortable. When she worries about the infected and whether everyone will be okay, Yi-hyun says they just need to focus on staying safe.

Sae-bom chides him for the very unsafe act of touching that blood and risking himself. Yi-hyun wonders if putting it on Joo-hyung was fine then. Sae-bom grumbles it's not like he made Joo-hyung eat it.

Upstairs, Young-ok is a mess. Woo-chang tries to calm her and suggests they give up on this place. That makes Young-ok the opposite of calm. If they leave and start over somewhere else, they won't make any money.

What does ease her mind is thinking of all the improvements and repairs they can take charge of at the complex once the lockdown is lifted. Young-ok decides she needs to ingratiate herself with popular residents to secure her place as the resident representative.

She marches over to Yi-hyun and Sae-bom's to apologize for locking them out, but she undercuts it by saying they really should've explained properly that they weren't infected. Sae-bom invites her in anyway.

Young-ok's attempt to win over Seo-yoon doesn't go so well, so she turns her attention to Sae-bom. She reminisces about young married life and asks how Sae-bom and Yi-hyun met. Young-ok spots the picture on the wall and starts to smile, but then looks aghast to see the teenaged Sae-bom in handcuffs. Ha.

Seo-yoon whispers to Sae-bom that she doesn't trust that ajumma. Sae-bom teaches her the adage to keep your friends close and your enemies closer.
