HAPPINESS

EPISODE : 10

Sae-bom heads to visit Se-hoon and sees his door is open a crack. While she cautiously enters, Tae-seok contacts Yi-hyun. He lies that Sae-bom's blood doesn't have the antibodies and instead encourages them to send Seo-yoon out; they're trying to get minors out of lockdown.

Yi-hyun asks if Sae-bom can leave with Seo-yoon. Tae-seok agrees under the condition she cooperate with his work. Yi-hyun says he'll get in touch after talking with Sae-bom and disconnects. Tae-seok observes to Ji-soo that it's not like Yi-hyun to send Sae-bom out and senses something's off.

On Yi-hyun's way upstairs, Sae-bom comes running and says there's trouble. Yi-hyun takes a subtle step back from her when she gets too close. She takes him to Se-hoon's and shows him a note. Se-hoon writes he committed a major wrong and couldn't endure anymore, so he left. He says to let everyone share his food and water.

The handwriting doesn't quite match the writing on his water container, and he left behind his phone and wallet. They rifle through his things, and Yi-hyun finds a pill container with Next. Everything almost too-neatly points to him being infected.

In the hall, they run into Se-kyu and Moon-hee who are hanging around to swipe Se-hoon's supplies. Yi-hyun and Sae-bom send them back for now and keep Se-hoon's disappearance a secret. Sae-bom doesn't see why a recluse would leave home and thinks foul play is likely.

Yi-hyun and Sae-bom can't find Se-hoon anywhere in the building, and the lobby door is unlocked. They head back up to 1501 and find the residents gathered. Andrew testifies that he saw Se-hoon leave the building this morning wearing his hazmat suit.

Since everyone is running out of water, Sae-bom and Yi-hyun eventually let everyone into Se-hoon's. They only let each person take what they need, stopping everyone (especially greedy Se-kyu) from cleaning out the place.

Joo-hyun is mad Yi-hyun didn't give the rich residents a greater portion of supplies and balks when Sang-hee claims Yi-hyun divided things fairly. He then asks Sang-hee if she noticed anything strange about Yi-hyun – he seemed to be sticking closer to Sae-bom than usual.

They're interrupted by a knock on the door. Young-ok and Se-kyu think leaving all that stuff in Se-hoon's apartment would be a waste. (These three are just about the most unpleasant clique ever.) Joo-hyung lets them in to discuss the situation and makes Sang-hee stand in the hall. Wow.

At home, Seo-yoon guesses that Se-hoon must've left because he was lonely. She saw something on TV about people with no friends or family dying alone. She worries about her parents, but Sae-bom assures her they're okay.

Sae-bom pour everyone some water, but Yi-hyun leaves his untouched all day. In the middle of the night, Sae-bom wakes to find Yi-hyun gone. She wakes up Jung-kook, but he doesn't know where Yi-hyun went.

Out in the hall, Yi-hyun sits on the floor, lost in thought. When Sae-bom comes out and sees the radio in his hand, she assumes he was talking to Tae-seok. He tells her she doesn't have the antibodies, which disappoints her.

Sae-bom notices the cut on his hand is bleeding again and drags him inside to treat it. As she checks his wound, he tells her about Tae-seok's proposal to send Seo-yoon out. He suggests she go with her, but Sae-bom says he should come too. Anyway, she's hesitant to send Seo-yoon out when they don't know how dangerous it is out there.

Yi-hyun apparently asked about Se-hoon, and Tae-seok said he'd look into it. But Sae-bom has another idea. What if he tried to leave but got scared and returned? Se-hoon could be hiding in the empty 1102.

They creep into 1102 and indeed find Se-hoon's water bottle. Then, they hear some ... interesting noises. Sae-bom bangs on the door and tells the couple to come out. Hae-sung and Sang-hee stumble out after their "legal consultation." Pfft.
