Min-seo, a welfare recipient, borrows Seo-yeon’s identity to experience the ordinary life of a woman in her twenties. Though small achievements help her regain the will to live, a web of forged documents and a rent scam soon strips everything away, leaving her back at square one. Initially intending to exploit Seo-yeon, Min-seo is deeply moved by her genuine warmth and ultimately confesses to her welfare fraud. From the ruins of her borrowed life, Min-seo makes a choice to start anew—this time, living under her true name.
