Setting time in 1950s.

Heeseung is just a man in his 30s who wants love. He has been in love, married once before, but it ended badly because his wife, whom he loves very much, cheated on him with someone else, just because he was too naive.

He has a wound in his heart and often blames himself that he is a flawed person, not worthy of anyone's love, and has built a wall from his last love that hurt him so much.

He is a judge who is skilled in his profession, but he is bad at making decisions for himself. He has lived like that all along until one day after getting off work as a judge, he stops by a bookstore and meets a person who is reading a book next to him.

It's you.
