The story of patients and the caregivers of a hospice department. It is the story of people who dream of 'well-dying'.
The former captain of Team Genie is facing his last moments of life. To grant his final wish, Tae Sik and Yeon Joo take him to his hometown, the East Sea. On the way there, they run into Gyeo Rye who is running away from his enemies. Although they meet by accident, their fate binds them together at the hospice hospital.
The new volunteer who will be driving the ambulance is Gyeo Rye. Although Yeon Joo does not like the idea, Tae Sik 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 Rye 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 Sik tries his best to grant her final wish.
Although Tae Sik'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 Rye 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 Rye 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 Rye, 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 Sik refuses to do, she acts on her own with some help from Gyeo Rye.
Gyeo Rye 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 Rye. She visits Jin Gu but leaves empty handed. As Seok Jun and Jun Kyung are in the brisk of finding Gyeo Rye, tension surrounds the hospice hospital.
It is now time for Sonny to have his final wish. Although Gyeo Rye thought that Sonny wants to take revenge on his previous owner, he realizes that it is not what Sonny wants. After his death, Gyeo Rye 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 Rye at the hospital. By threatening him that she will die, he follows her against his will. Even without saying goodbye, Gyeo Rye 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 Rye 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 Sik'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.
On the way to Mokpo to fulfill Chang Woo's final wish, Tae Sik collapses because of his cancer. Although he is fine for now, he promises Gyeo Rye and Yeon Joo that he will receive chemotherapy once they return to the hospice. Meanwhile, the secret behind the patient in Room 403 starts to uncover itself slowly
Jae Yeon and Ho Yeon are scared that they will be left alone if their grandmother passes. However, Gyeo Rye feeds them and gives them work to do in the hospice. Meanwhile, the man in Room 403 wakes up and talks to Gyeo Rye. He wishes to leave the hospital once he gets his memories back
Jae Yeon and Ho Yeon's grandmother passes. Although Gyeo Rye wishes to take them in, they already have an Auntie who wants to take care of them. Meanwhile, it turns out that Yoon Ki Chun has never lost his memories in the first place. Without anyone knowing, he plans an evil scheme in the hospital.
Yoon Ki Chun calls upon his gang to the hospital. He is still the man he used to be and plans to take away everything that Tae Sik loves. Meanwhile, Tae Sik helps Jun Kyung to be free from despair. With his help, she learns the truth behind the reason why she ended up in an orphanage.
Ki Chun and Tae Sik become hospitalized. While Ki Chun is bleeding out, Tae Sik's cancer becomes worse as his body is severely injured. Meanwhile, Gyeo Rye finally ends his relationship with Ki Chun. With nobody to bother him anymore, he goes back to where he truly belongs in Woori Hospice Hospital.
The time for Tae Sik's final wish has come. Although Gyeo Rye thought it is to hold Tae Sik's early funeral, it is actually a different event for Gyeo Rye. After Tae Sik's passing, his will to help those in need does not change. The hospital makes a foundation that helps Team Genie to grant people's wishes more actively
