The new volunteer who will be driving the ambulance is Gyeo-re. Although Yeon-joo does not like the idea, Tae-shik brings him here so he can learn a lesson. The first patient he will be driving is Mr. Pyeon, who might die in a week. Team Genie brings him to his old home as he wishes to face his last moment where he has his most beautiful memories.

Yong-ho now faces the last moments of his life. Watching him pass makes Gyeo-re feel something he never felt before. A young patient fights extreme pain due to cancer. For the girl who is not sure whether to live in pain is better than dying, Tae-shik tries his best to grant her final wish.

Although Tae-shik’s attempt to persuade Gyu-tae seems meaningless, Gyu-tae suddenly changes his mind for some reason. Hence, the preparations for Se-hee’s musical officially begin. Meanwhile, Gyeo-re is still obsessed with what is in Room 403. Although he knows that the ghost is a lie, he is still curious.

Se-hee’s final wish ends with a success. Her musical brings her loved ones together and also helps Gyu-tae to repent. Meanwhile, Gyeo-re finds some suspicious things about Mr. Kang. Although Team Genie is a charity group, he sees Mr. Kang receive money from Se-hee’s parents.

Jun-kyung is now out of prison. Although Seok-jun finds her to get to Gyeo-re, she is also unable to reach him. Seo-jin’s boyfriend becomes the victim of a hit-and-run case. Not knowing when he might die, he whispers his final wish to Seo-jin. As the wish is something Tae-shik refuses to do, she acts on her own with some help from Gyeo-re.

Gyeo-re expresses his feelings toward Yeon-joo for the first time. Although the timing is not intentional, he still means what he said. However, Jun-kyung is close to finding Gyeo-re. She visits Jin-gu but leaves empty-handed. As Seok-jun and Jun-kyung are in the brisk of finding Gyeo-re, tension surrounds the hospice hospital.

It is now time for Sonny to have his final wish. Although Gyeo-re thought that Sonny wants to take revenge on his previous owner, he realizes that it is not what Sonny wants. After his death, Gyeo-re pursues happiness at the hospice hospital. Sonny and the people at the hospital teach him what it is like to have a family.

Jun-kyung finds Gyeo-re at the hospital. By threatening him that she will die, he follows her against his will. Even without saying goodbye, Gyeo-re leaves the hospital and breaks Yeon-joo’s heart. Although the brother and sister live together as a family now, every day is nothing but torment for the both of them.

Gyeo-re is able to escape Jun-kyung and come back home safely thanks to Yeon-joo. As he returns to the hospital, he becomes certain that this is where he belongs. Tae-shik’s cancer is getting worse. Yeon-joo is worried that he might not have much time left and that he is still unaware of the secret of Room 403.
