밥 잘 사주는 예쁜 누나

Jin A is a competent career woman in her 30s who is highly regarded by her boss. However, life as a grown-up is not easy. She grows increasingly lethargic from her company's unfairness and lack of sexual morality, her continuing romantic failures, and her parents who try to rush her marriage. Just then, Jun Hee, a friend of Jin A's brother whom she knows little about, returns from the US. They meet after a long time and begin to see each other in a new light. Jin A is flustered and intimidated by Jun Hee's swift and refreshing approach, but can't stop her feelings from developing. Jun Hee knows he shouldn't express himself to his sister's friend after seeing her in a while, but can't help it. He wishes Jin A to become his woman, and not just someone who buys him meals. Will these two acquaintances be able to begin true romance?
