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.
