There are three sisters in the family. The eldest and second sisters are always good topics for their mother to talk about when they get together. But when it comes to the youngest daughter Chunxin (played by Lee Ji-eun), her mother's face immediately changes. This is Lee Chunxin's life so far. She is average in study, average in appearance, and extremely bad in luck. Various resumes have been ignored, and she failed in various selections. She finally found a part-time job in a hotel, and because of an accident, she offended the president of the entertainment company Shin Junhao (played by Cho Jung-seok) and was resigned. But Chunxin's heart is not ordinary. No matter how big the blow is, she can resolve it one by one, and finally she can magically turn danger into safety, and her fate with Junhao begins. Chunxin, who is emotionally rich and extremely easy to trust people, has encountered many setbacks on the road to growth, and Junhao, who seems to be smooth sailing, also has unknown bitter past behind him. The two gradually understand each other from the initial grudge. And happiness is waiting for this group of ordinary and kind people not far away.
