The story unfolds as the story of two Meiko, one Fumiko from the island and Takamiko from the city who become friends after a lot of quarrels and ridicule.The two became so close that they could not be separated, until an event separated their friendship forever.When Takamiko tried to dive in unfavorable current conditions, Fumiko accompanied her friend on what turned out to be her last dive.That's why Sang-tae has held a grudge against Kao Miko all these years and can't forgive her for what she did.

Now, Shangtai hurriedly ran to the shore and saw Gao Miko being carried into an ambulance, followed by her family.At the same time, Rong Bi learned that Gao Meizi was taken to the hospital, and he rushed there and called Sanda on the way to ask her to stay calm.Takamiko's family arrived at the hospital quickly, but their father was too panicked to answer the doctor's questions.Just then, Rong Bi arrived and answered the doctor's questions.He told the doctor that Takamiko suffered from arrhythmia and provided the medications she had been taking and other relevant information.Takamiko's daughters are shocked by the condition she has experienced over the past eight years.

Rong Bi was asked about Sanda's situation, but she finally exploded, accusing Rong Bi of concealing Gao Meizi's health and lying about her ignorance.Rong Bi explains that Gao Meizi doesn’t want to tell the sisters, but if Sanda had visited Gao Meizi in the past eight years, she would know the truth.Sanda felt guilty and realized that it was because of Rong Bi that she did not return to the island.Sang-do tries to visit Sanda and the others in the hospital, but is stopped.The Haenyeo take care of Ha Sol while discussing Go Mija's situation.Ha Sol goes to the beach and meets Ji Chan and bursts into tears while worrying about her grandmother.The sisters cared for their mother all night and tried to prevent her from leaving the hospital the next day, but failed.Rong Bi drove the sisters home, and the Haenyeo waited for Gao MeiZi's return.That night, the sisters got drunk and promised to take care of their mother and prevent her from diving again.

The next day, Sanda called Rong Bi to apologize, but she was surprised when the other party apologized to her first.This made Rong Bi recall a memory from their past and was deeply moved.Meanwhile, Kyung-tae and Eun-woo discover that Yong-pil has been staying in Sandari for Go Mi-ja, and has taken care of her every time she dives, even covering her buoys with patterned floral fabrics.On the other side, Sang Tai also discovered this and remembered seeing the cloth in Yong Bi's room.Feeling angry, he found Yong Bi late at night and told him to go to Seoul.Unable to suppress his emotions, Yong Bi explodes at him, telling Sang Tae that he cannot hate Gao MeiZi as much as he does.He also felt the pain of losing his mother and not being able to be with Sanda, but had never spoken of these words until now.But no matter what, he knew that his mother's death was not because of Takamiko, and would never blame her like his father did.

Jingtai was drunk and Sanda walked in. He told Rong Bi that he gave up his dream to take care of Gao Meizi.Sanda is shocked and Eun-woo tells Yong-pil what happened.Rong Bi looked around for Sanda, found her drunk, and tried to take her home.However, Sanda could no longer suppress her feelings and confided to him the eight years of suppression.She told him that because of him, she had not returned home for eight years, kept distance from her friends, and tried hard to forget him.Now, he kept asking her if she was okay, and she wished she could rely on him again, but knew that wasn't possible.She starts to walk away, but Rong Bi stops her, allowing Sanda to finally break her guard and kiss him.
