Sae-bom returns to the infected zone to save Yi-hyun in ‘Happiness’

According to Soompi, Happiness’s producer teased, “The shocking truth of the infectious disease situation, including the treatment, will be revealed. The final episode will be filled with suffocating tension and lingering feelings.” This was certainly true as Sae-bom returns to the residential building. Tae-Seok (Jo Woo-Jin) gives her one of the only antidotes made with her blood. Instead of using it for Yi-hyun, she administers it to Seo-Yoon’s (Song Ji-Woo) mother.

Sae-bom passes the barricade and re-enters the building. Fans learn what has happened in the meantime during her absence. Yi-hyun gave into his thirst and bit Andrew (Lee Joo-Seung). He and the other tenants check on the others in hopes of finding Andrew, who has likely turned.

Meanwhile, Sang-hee (Moon Ye-won) and Hae-sung (Park Hyoung-soo) try to figure out the passcode to Joo-hyeong’s (Baek Hyun-jin) bank account. Joo-hyeong took the Next pill after Sang-hee attacked him.

While the remaining tenants are bloodied but alive, Yeon-ok (Bae Hae-sun) convinces Joo-hyeong to try and kill Yi-hyun. He takes Sang-hee hostage and cuts her to entice Yi-hyun with her blood.

Yi-hyun escapes to the apartment to control his thirst, not wanting to become a monster. Thankfully, Sae-bom arrives and calms him. They share their first kiss.

Tae-sok and a crew of soldiers return to the building after So-yoon’s (Jung Woon-sun) testimony that some of the infected never turned. They sequester the remaining tenants to take them back to the research facility.
