Black Healing Korean drama, adapted from the novel of the same name by writer Seo Eun-chae, Kim Lanyu (played by Kong Ming) and Jung Heewan (played by Kim Min-hee) both have a crush on each other in both directions, but before they confess to each other, Kim Lanyu died. Jung Heewan has been cheerful and innocent high school student, and instantly becomes a young man who has no desire for life and lets youth pass away.

Suddenly, a week before her death, childhood sweetheart and first love Jin Lanyu appeared in front of her again. This encounter was unusual. As the messenger in the underworld, Lanyu told her that there was only one week left. Zheng Xiwan was encouraged to make a bucket list and decided to fulfill her unfulfilled wish for the rest of the days and rekindle her frustrated life. The two realized their wishes one by one, and at the same time, in the process of regaining their past emotions, they jointly searched for the meaning of life and the fantasy romance of love.

Jin Lanyu came to Encheng High School as a transfer student. She was quiet and introverted and got her deskmate with Zheng Xi, who was lively and cheerful in the class.On April Fools' Day, the students in the class suggested playing the game of exchanging names, and Zheng Xiwan happened to get Jin Lanyu's name.All day long, she chatted and joked with her classmates as “ Jin Lanyu, and felt very happy.

After school, Zheng Xiwan smiled and said to the real Jin Lanyu that the name seemed to bring her good luck and made her have a particularly happy day.From that day on, Zheng Xiwan would occasionally joke that he was ” Jin Lanyu %, and even half-seriously said that he wanted to use this name all the time.

Jin Lanyu's death four years ago caused Zheng Xiwan's life to fall into a long silence.One day four years later, a familiar figure quietly appeared beside her.Jin Lanyu appeared in front of Zheng Xiwan in a black windbreaker with a gentle smile on her face.He told Zheng Xiwan that she had only one week left.

She could not believe that the person who had long passed away would appear as a messenger in the underworld. For several consecutive days, she deliberately avoided Jin Lanyu and turned a blind eye to his appearance.When asked about the wish she wanted to fulfill, she just shook her head in a silence.Jin Lanyu did not force it, but hoped that she could accompany him to complete the unfulfilled bucket list.

Zheng Heewan and Jin Lanyu spent many happy times in school, and those tiny daily life have now become precious memories.Seeing Zheng Xiwan gradually closed herself, Jin Lanyu decided to take her back to her alma mater, hoping that the familiar scenes could awaken her passion for life.

However, when Zheng Xiwan stood at the gate of the former school, her face became paler, and those beautiful memories only made her feel suffocating pain at this moment.She turned and left, as if she could escape from the place and escape from the past that broke her heart.Jin Lanyu stood there, looking at her back as she was walking away in a hurry, with deep helplessness and pity in her eyes.

Zheng Xiwan finally confessed her true thoughts to Jin Lanyu. She said that those common memories now only bring unbearable pain to herself. Whenever she thinks of the past, it feels like she is sprinkling salt on her wounds.Instead of relive those beautiful times that she can never go back to, she would rather choose to completely forget.

Looking at Jin Lanyu's lost expression, she cruelly refused the proposal of the two to continue completing the bucket list together.The next day, Zheng Xiwan went to find their first common friend Li Hongxi, but when Li Hongxi looked up and saw Zheng Xiwan, he turned around and left without saying a word.

Afterwards, Zheng Xiwan found Yoon Tae-jing again. She carefully asked Kim Lanyu's mother Kim Jong-sook about her recent situation, but the other party was silent for a long time, and finally just said coldly that it was inconvenient to disclose.Jung Heewan really wanted to tell Kim Jong-sook face to face that it was her fault when Kim Lanyu's death was not her fault.

At this time, Jin Lanyu gently patted her on the shoulder, saying that the past should not be carried by her alone, and that those self-blame and regret will only leave her trapped in the cage of memories forever.He told Zheng Xiwan that the meaning of life lies not in the past, but in cherishing every moment of the present.

Time passed like an hourglass, and Zheng Xiwan suddenly realized that the last week of her life was almost gone. In the only twenty-four hours she had left, she decided to say goodbye to the world, and she personally prepared gifts for her sister and father.And she took the initiative to take Jin Lanyu's hand, and the two of them had an ordinary date like ordinary couples.

However, just when she wanted to immerse herself in this last tenderness, the college senior who could see the ghosts and gods called her.Zheng Xiwan held his phone tightly and looked at the last sunset in the sky, with nostalgia and determination intertwined in his eyes.
