Ha Won realized that he could have a good night's sleep since someone is with him through the night. He asked Seo Woo to visit and stay in his place anytime.
Seo Woo wishes to return the AI box (Ji Soo) in Soon Ho's apartment. She doesn't want Ha Won to know she took it and listens to Ji Soo's voice. Seo Woo thought of Ha Won as she reached her home. Ha Won's words lingered to her mind.
"Stay with me. I need you. I miss you, and I want to hold you."
Those words filled Seo Woo's heart with joy that she chose to live and stay with Ha Won this time.
In-Sook confesses with Soon Ho that his wife has died, and he misses her terribly. Playing the song relieves his loneliness and reminds him of Ji Soo. In-Sook started to do his first single piano recording. Soon Ho is proud of him and cannot wait to release it to the public.
The day has come, Seo Woo finished to polished the song, and it is ready to be released.
In-Wook smiled with his latest achievement. Though alone in his house, he felt good now after a long time of grief. Soon Ho, together with Seo Woo, celebrated as the single was released. Seo Woo shared it with Ha Won and friends. They congratulated her work and the start of more projects to come.
Ha Won cooked dinner to celebrate Seo Woo's achievement as a music engineer. After their meal, they sit together, looking at the sky with evening tea. Seo Woo asked Ha Won why he didn't want to see the snow nor hear the sounds of the snow. Ha Won shared that his mother died due to the heavy blizzard. Since then, life in Oslo has changed his heart.
In-Wook heard Ji Soo's voice at the studio while Seo Woo turned on the AI box. He rushed to check, but Seo Woo hid it right away. She went out, leaving In-Wook behind. He felt depressed thinking of his wife. Soon Ho invited him to go out and talk in one of the shops near the studio. In-Wook confessed that his wife disliked him when he admitted an accident that he got involved with. Ha Won's mother died not because of the blizzard, but when In-Wook told her to go in another direction to find her son - Ha Won. Ji Soo felt depressed about hearing the truth. Ha Won never knew the real reason until she died.
Ha Won found a letter from Ji Soo. It says about reasons for his mother's death. But Ji Soo tells the story in the next letter where he can't find it.
Ji Soo knew that her husband In-Wook had inadvertently killed Ha Won's mother when he was still in high school back in Oslo. He misled Ha Won's mother to a different location, and she got stuck until a blizzard caught her. Since then, no one knows the reason but only In-Wook.
In-Wook married Ji Soo and they transferred to Seoul when In-Wook received an invitation to play his music live. In-Wook shared with Ji Soo the incident, which led to their painful breakup.
Soon Ho and Ha Won are relatives, and they knew Seo Woo. Soon Ho knew In-Wook as a musician but not as the husband of Ji Soo. Ha Won knew In-Wook as one of the musicians who use their studio but hasn't met him. He never knew that In-Wook is the husband of Ji Soo.
Soon Ho is not aware that In-Wook is the person they are looking for.
