Meng Qi lived in a luxury apartment whose rent was paid by Cheng Jichuan, and spent five years without asking what came next. She thought that if she never discussed marriage, she wouldn't be hurt by the things that came with it.
The night before registering her marriage, Qiao Manning dragged her suitcases into the apartment. She brought a shared savings account that had been tampered with without permission, a fiance who claimed he had "only met up with an old acquaintance," and a wedding she didn't know whether to go through with.
At first, they only planned to live together for a few days. Later, different men came and went: some gave money, some gave rings, some made promises, and some left behind only the tie they hadn't taken with them the next morning. Cheng Jichuan suddenly put a deadline on their five-year relationship, while Qiao Manning walked through that door despite knowing her marriage was already cracked.
From then on, keeping someone, marriage, fidelity, desire, dignity, and betrayal all came with a price in that apartment.
Gradually, they understood that the most expensive things were never rent, jewelry, or the money divided up in a divorce. It was knowing a relationship had already gone bad and still being unable to bear leaving first.
There are no innocents in this apartment, only debts of love that must eventually be settled.
Premise: Explore the complicated boundaries between marriage, money, desire, and fidelity, and show how adults bear the cost of dependence, betrayal, and their own choices.
