Baek Sehee is a successful young social media director at a publishing house when she begins seeing a psychiatrist about her—what to call it?—depression? She feels persistently low, anxious, endlessly self-doubting, but also highly judgemental of others. She hides her feelings well at work and with friends, performing the calmness her lifestyle demands. The effort is exhausting, overwhelming and keeps her from forming deep relationships. This can't be normal. But if she's so hopeless, why can she always summon a yen for her favourite street food: the spicy rice cake, tteokbokki?

Yeongju is burned out. With her high-­flying career, demanding marriage, and busy life in Seoul, she knows she should feel successful, but all she feels is drained. Yet an abandoned dream nags at her, and in a leap of faith, she leaves her old life behind. Quitting her job and divorcing her husband, Yeongju moves to a small residential neighborhood outside the city, where she opens the Hyunam-dong Bookshop.

In a small, tidy apartment on the outskirts of the frenzied metropolis of Seoul lives Kim Jiyoung. A 30-something-year-old “millennial everywoman”, she has recently left her white-collar desk job - in order to care for her newborn daughter full-time - as so many Korean women are expected to do. But she quickly begins to exhibit strange symptoms that alarm her husband, parents, and in-laws: Jiyoung impersonates the voices of other women - alive and even dead, both known and unknown to her.

Yeongju did everything she was supposed to, go to university, marry a decent man, get a respectable job. Then it all fell apart. Burned out, Yeongju abandons her old life, quits her high-flying career, divorces her husband, and follows her dream. She opens a bookshop. In a quaint neighbourhood in Seoul, surrounded by books, Yeongju and her customers take refuge. From the lonely barista to the unhappily married housewife, and the writer who sees something special in Yeongju - they all have disappointments in their past.

Yunjae was born with a brain condition called alexithymia that makes it hard for him to feel emotions like fear or anger. He does not have friends - the two almond-shaped neurons located deep in his brain have seen to that - but his devoted mother and grandmother aren’t fazed by his condition. Their little home above his mother’s used bookstore is decorated with colorful Post-it notes that remind him when to smile, when to say "thank you", and when to laugh. Yunjae grows up content, even happy, with his small family in this quiet, peaceful space.
