Kang Hoon-Nam is charming, handsome, and an expert on the theories of romance, but he has no interest in falling in love himself. Yoo Jung-Eum, a former athlete who once dreamed of romance, has given up on finding love after being worn down by the realities of life. Instead, she becomes a relationship counselor, helping hopeless singles find their perfect matches. Their paths collide when Jung-Eum’s work brings her into Hoon-Nam’s orbit, and the two quickly clash over their very different views of love. But as they help their romantically challenged clients navigate the complexities of relationships, Hoon-Nam and Jung-Eum gradually begin to break through each other’s defenses.
