Saranghaneun Jonjae

Soyou, who was a promising track and field athlete, lost everything due to acute heart disease. She was sentenced to death but miraculously survives with a heart donation. She loses everything she had built up and returns to high school a year later than her peers, but it is not easy for her to make friends or pursue her dreams. Then, in the new semester of the second year, the moment she sees a boy in the classroom, her heart suddenly races, and she feels like crying... The man she met in her dream that night introduces himself as the owner of the transplanted heart and the father of the boy she saw for the first time today. Isn't that something? His son, Jaeha, has lost his entire family and is alone in this world... At the man's request, Soyou gives Jaeha a message of support, and with each action, precious people are found in Soyou's empty life—reasons for life, relationships, and dreams. Soyou progresses slowly, but one by one, she learns how to live.
