Jiang Ruoxi is an unlucky time traveler. When she wakes up, she finds that she has become a passerby in the comic book world. There is no system or plug-ins. The only advantage is that there is a greedy neighbor living next door - the bankrupt Miss Mari Hojo who is known as the "rent collector". In order to survive, Jiang Ruoxi was forced to battle wits with this money-lover. On a daily basis, she was extorted money, tricked, and used as free labor. One day, Mari Hojo suddenly asked him with red eyes: "Are you using me?" Jiang Ruoxi was confused on the spot - he was just helping her repair the water pipes! A misunderstanding led to an affectionate confession, and the style of the two changed dramatically from then on. Jiang Ruoxi was in charge of making jokes, and Mari Hojo was in charge of rent collection. The two of them embarked on a journey of survival full of laughter in the world of comics.
