HAPPINESS

EPISODE : 11

In the hall, everyone waits nervously. This was Joo-hyung's plan, and everyone else claims they didn't know Andrew was the killer. Inside, Andrew reveals his face now that his ruse is up. He takes Seo-yoon hostage and since he has a gun, there's nothing Sae-bom can do but promise Seo-yoon she'll come for her.

Everyone outside is surprised to see Andrew without the mask. He orders them all to the gym and says he'll bring Sae-bom and Yi-hyun down. They want their food now, but no one dares defy the killer with a gun. He orders Hae-sung to stay behind.

When the gang in cahoots with Andrew meets Hyun-kyung and So-yoon in the stairwell, they hide what's going on upstairs. Young-ok convinces the women to go with them to the gym so they don't find out about the group's betrayal of Sae-bom and Yi-hyun.

While Sae-bom treats Jung-kook's stab wound, Yi-hyun shakes from both the effort of holding himself back and his fear for Jung-kook. Sae-bom steadies him and vows to put everyone responsible away once they leave.

Yi-hyun steps aside and radios Tae-seok to explain the situation. He warns that Seo-yoon will be in danger if Tae-seok storms in. Yi-hyun also shares that he knows Tae-seok lied to him and that Sae-bom has the antibodies, which Tae-seok basically admits.

Andrew leaves Seo-yoon in Hae-sung's care and goes back inside the apartment. Yi-hyun confronts him, having recognized his face from a police station wanted poster. He asks how many people Andrew has killed.

In flashback, we see him kill Ahn Gook-jin and steal his identity. We also see him kill the cleaning ajumma. Andrew argues he's no different than the infected who hide their true nature and wait to strike. (Ah, so he isn't infected, just your run-of-the-mill serial killer.)

In the gym, Joo-hyung reveals he saw Andrew dragging away the cleaning ajumma's body. Andrew went to kill him too, but Joo-hyung made himself useful by suggesting he hide the body in that empty apartment. He even gave him the idea of making it look like she was bitten.

Joo-hyung went to Young-ok immediately afterwards, and they struck a deal to let Andrew do whatever he wanted so long as he helped them with problem residents. Geez. These three deserve each other.

Back in the apartment, Andrew explains he got Se-hoon to open the door by saying Sae-bom was hurt and needed supplies. He then forced him to write that letter. That's when Joo-hyung saw the bag of lime in the apartment and suggested Andrew use it to cover the smell.

Andrew takes Sae-bom and Yi-hyun down to the gym and passes their radio over to Young-ok. She begs for help, but Tae-seok ignores her communication. Everyone is horrified to realize Sae-bom and Yi-hyun have had contact with the outside this whole time and could have reported on their criminal actions.

Young-ok tries to take control of the situation and reminds everyone that Yi-hyun and Sae-bom agreed to turn on the emergency generator. Andrew tells everyone that they can just blame everything on the "crazy man with a gun."

Hyun-kyung bravely stands up to him and asks if they're supposed to turn a blind eye to his crimes. Even though she's frightened when he approaches menacingly, Hyun-kyung holds her ground. When he puts the gun to her chest, Sae-bom intervenes.

Once Andrew lets Hyung-kyung go, Sae-bom sends her out and asks So-yoon to watch Seo-yoon. Andrew says he'll let Jung-kook and Seo-yoon go once Yi-hyun and Sae-bom come back from turning on the power.

Upstairs, Jung-kook tries to convince Seo-yoon he's okay despite the gaping wound in his side. Hae-sung goes to take Seo-yoon to his apartment, but she isn't keen on leaving.

So-yoon arrives and confronts Hae-sung, asking if he helped Andrew. She's shocked that her husband who used to be a dedicated public defender would do something like this, but Hae-sung argues he got nothing in return for his goodness.
