These are two people who have been trapped by love.
One cannot love, the other has been abandoned by love. In this ancient city that has been shrouded in smog for half a month, two lonely souls meet by chance and then live together.
The following conversation took place before moving in together:
Jin: "If I pass the interview, can I live with you?"
Meng: "What do you think?" I don't even bother to type in the punctuation marks.
Jin: "According to what you said the day before yesterday, it's okay."
Meng: "That's okay"
Kim: "I will work hard to pass the interview."
