After her family falls into financial ruin, Seo Eunha drifts from one part-time job to another just to stay afloat. Then one day, on the street, she unexpectedly runs into Han Wonseo, her long-lost first love and ex-girlfriend. "We never even broke up." Wonseo pushes her way back into Eunha’s life, insisting they were never truly apart. Though Eunha feels a flutter of excitement, reality soon sinks in, she’s drowning in debt, and fear keeps her from accepting Wonseo’s love. Then the news hits: Eunha’s tiny studio apartment is slated for redevelopment. Now, she’s desperate to find a new place to live. And just like that, almost as if she was waiting for it, Wonseo reaches out with an offer. "You need money, don’t you?" Despite the resentment, heartbreak, and buried feelings, Eunha finds herself drawn back into a deep, complicated relationship with Wonseo once again.
