“What kind of crazy woman lives with her ex-husband!” …Well, she exists. Right here. Dan-bi, who was scammed in a jeonse (housing lease deposit) fraud and is on the verge of being thrown out on the street, tracked down the current landlord and begged to stay in the empty house just until she could secure her deposit back. But that landlord turned out to be her ex-husband, with whom she had a one-year contract marriage before separating!​ Unexpectedly, her ex-husband easily accepts Dan-bi’s request. “But there’s already someone living in that house.” “……Who?” “Me.”​ Dan-bi suddenly finds herself cohabiting with her ex-husband Do-young. Can the two of them finish their cohabitation sweetly and lovingly… or safely?
