Seo Haena is a girl who has to avoid the sun due to a rare disease called xeroderma pigmentosum, therefore she's only active at night, when she's used to go busking at the train station with her guitar. From her bedroom's window, every day Haena sees a high school boy with a surfboard with his friends. Haena is intrigued by him and, one night, while she's singing and playing the guitar outside, she sees him passing by, therefore she follows him and clumsily introduces herself. Noting that the boy wears the same school uniform as her, Haena's friend Bom offers to spy on him, and discovers his name is Jung Haram.

The next evening, Haena sits on a bench at the train station, and Haram arrives with his surfboard. Both embarrassed, they start talking, with Haram eventually promising to meet her and listen to her sing the next night. When they meet up, another street performer has occupied Haena's spot, so Haram takes her to a square, where a crowd gathers to hear her sing and play the guitar. Afterwards, they share their dreams about the future while watching the sea, and Haram asks her out.

Their date ends abruptly as the sun breaks and Haena rushes back home: Haram is therefore informed of her condition and, although initially taken aback, starts reading medical books to better understand. For a while, Haena stubbornly refuses to see him, while Haram takes up small jobs and sells his surfboard to pay for a recording studio where she could record her debut single. One night, Haena's father, out of concern, invites Haram over for dinner, and the boy reveals his plans for Haena's CD. As they walk home that night, the two begin to talk, and Haena slowly realizes how much Haram truly cares for her.

As her medical condition begins to worsen, the girl loses feeling in her hands, and is unable to play the guitar. Meanwhile, Haena and Haram enjoys their time together, going on dates like an ordinary couple, and she assures him that she still has her voice and wants to sing for him. In the studio, Haena asks her father and friends to leave and wait for the CD to hear her song.

Some time later, as promised, Haram brings Haena to the beach to watch him surf. She is in a wheelchair and wearing the protective suit she had left hanging for years. With a painful expression, her father tries to convince her that if she takes off the suit, she could run around freely, but she declines, saying she wants to live until the end. She then tells Haram about a city called Nordkapp in Norway where the sun never sets in summer, and about her wish to sing there one day under the midnight sun. While telling the story, Haena quietly dies.

Later on, Haram and Haena's friends and family listen to Haena's song, "Good-Bye Days", on the radio as it's finally released. With "Good-Bye Days" playing in his headphones, Haram goes to Nordkapp and meets Haena's ghost. The two hug promising to meet again underneath the sun so as not to be lonely, and be there for each other.

Midnight Sun was a box office success, selling out tickets during its run, and drawing favorable reviews from domestic as well as global audiences.^[10] Praises were directed to its melodic numbers, the lyrics, the stage directing and the moving performances of the actors.^[19][44][45] After two weeks, the online screening attracted 26,000 people from 80 countries,^[46] reaching 82,731 audiences from 114 countries by the end of its run.^[29] The number of offline and online audiences were similar, with 70% of the online audience made by foreigners.^[47] The sitzprobe, which aired online on April 24 before the opening, attracted 20,000 people.^[18]

Next Daily highlighted the faithful reproduction of the scenes from the original work, which were reinterpreted with a musical feeling, as the strength of the play, and stated that Haena and Haram's pursuit of the ordinary made people reflect on the new concept of normality brought about by the COVID-19 pandemic.^[48] However, it lamented that the short running time hindered Midnight Sun from showing the two main characters' emotions more delicately.^[48]

For The Voice of the People, "The development and subject matter presented universal emotions such as the freshness of a first love, the affection and the sadness of a terminally ill patient, and a family member watching over them. You can feel the familiarity that anyone can relate to, but on the other hand, it is also banal. There is no dramatic development, but you can find a quiet laugh in the cute stories such as the tactless first meeting, the affectionate unrequited crush, and the thrilling first love, and a familiar emotion is guaranteed in the story of Haram and Haena's family, who stay by Haena's side until the end."^[49]
