Tae-oh goes to see his mom, thanks to Seon-yeong's help, and he finds out what his mom's been hiding from him. Hyo-ri goes on an overnight trip with Bo-hyeon, and so do Ji-an and Jeong-seok. After the mother and daughter's happy trips, Ji-an receives news that Hyo-ri's surgery has been moved up, and she hopes her daughter's surgery will bring them spring again.

Hyo-ri's surgery date gets moved up, and the residents of Cheonghae offer comfort and support to Hyo-ri and Ji-an in their own ways. Jeong-seok reassures Hyo-ri that he will stay by Ji-an's side, no matter what happens. Meanwhile, Ji-an tells Jeong-seok who the birthmother of Hyo-ri was and how Hyo-ri was raised.

Before her surgery, Hyo-ri confesses to her mom that she is the best kind of mother she could ever had. After Hyo-ri returns from surgery, Bo-hyeon tells her he wants to go study in Germany. Inspired by what Bo-hyeon said, Hyo-ri decides to pursue studying medicine.
