The story in the beginning was nice with Ji‐Hyo looking for her boyfriend, Si-kook (Even after they broke) assuming he was taken by aliens then assuming the was also kidnapped by a church cult.
I didn't like Ji-hyo's friend though, she was nosy and annoying sticking her nose in places it shouldn't be in.
The show has it ups and downs as every show does. Ji-hyo and Bo-ra are strong independent women, they smoke and curse. They don't need a man's help. A down though is that the show drifted away from the main goal in the end. There was Cults and religion that was suddenly added to the mix.
