*This article contains spoilers. JTBC TV Series "Prefabricated Family - Where Our Love Lies" EP8 (viewership rating: 3.4%) is about Sang-ha (Hwang In-Yeopp) and his sister
Sang-ha and Dae-wook (Choi Moo-sung) headed to Seoul and found their mother, Jeong-hee (Kim Hye Eun), safe and sound.
They were relieved. Then they ran into Sohee, who looked cheerful. Sohee didn't understand the seriousness of the situation. Sangha said to her, "Sohee, should I stay with you instead of your mother?" and replied, "I'll take care of you."
"I'll stay with Sohee for a bit. You can't come to the hospital by yourself and take care of Sohee too. You go home first. I'll come over in a few days," he suggested.
Dewook objects, saying, "No. Why would you take care of a young child?" Sang-ha worries about the school, saying, "It's only for a few days, isn't it?"
"It's okay until she accepts it. I can't let Sohee see her mother right now. She's still a small child. Someone needs to be with her."
But Daewook didn't accept it, saying, "Why you?" Sangha replied, "Then who else is there besides me? When Mom wakes up, she'll start looking for Sohee.
I will check if it's okay and then I will be there right away."
