Choi Han-su, who's fallen on hard times, decides to leave the city and return to his hometown. Soon, he bumps into his old classmate Jung Eun-hui.

The class reunion ends with a tiff. Eun-hui considers a startling suggestion from Han-su, unaware that not everything with him is all it seems.

When Eun-hui leaves on an overnight getaway with Han-su, her concerned friends discover the secrets he's been keeping from them all.

When Park Jeong-jun chases off her annoying admirer, Lee Yeong-ok asks him to go for a walk. At work, the other divers disapprove of her methods.

Bang Yeong-ju plans to graduate high school and leave the island behind, but an unwanted roadblock threatens everything. Jung Hyeon worries about her.

At a low place in her life, Min Seon-a finds herself heading to Jeju. Seeing her again brings back aggravating memories for Lee Dong-seok.

Committed to their decision, Yeong-ju and Hyeon agree to stop hiding their situation. Coming clean to their fathers is the toughest ordeal.

Bang Ho-sik and Jung In-gwon each vehemently disagree with their children's wishes. An unbudging Yeong-ju leaves home for a motel.

When Seon-a is nowhere to be seen, Dong-seok leaves to find her. When he does, she offers answers to the questions he always had, but never asked.

Ahead of an all-important decision that is out of her hands, Seon-a heads back up to Seoul for her son's birthday. Dong-seok accompanies her.

Seon-a shares her next steps with a supportive Dong-seok. Yeong-ok ignores being cast out by the other divers, and enjoys a date with Jeong-jun.

Yeong-ok has a close call in the water. Everyone in the village eagerly welcomes back Ko Mi-ran, but Eun-hui seems noticeably on edge.

Left alone in Eun-hui's house, Mi-ran cannot resist the urge to read her friend's diaries. Hurtful revelations follow.

Yeong-ok abruptly pushes Jeong-jun away when her closely guarded secret threatens to make an appearance on the island.

Jeong-jun sticks by Yeong-ok's side and gets to know her visitor, who has yet to show anyone the drawings in her sketchbooks.

Hyeon Chun-hui finds her hands full when her granddaughter is dropped off at her house for two weeks, and wonders if something might be amiss.

An overheard conversation leads to heartbreak for Chun-hui. Son Eun-gi tells the villagers about all the wishes she wants to make.

Upon hearing major news about his mother, Dong-seok does not know exactly how to feel. He deliberates over a request she's asked of him.

Dong-seok and Ok-dong make a series of impromptu detours on their way back home. Their time together allows old wounds to heal.
