Doona" tells the story of a girl who was a K-pop idol but left the band due to health issues and started living in solitude. One day, a boy moved in next door to her in a building where the neighbors share a common yard. Living a solitary life, she often found herself in pain, and the boy would always help her. Gradually, she began to feel a sense of closeness toward him, and their love story began.I was eagerly anticipating a scene where he would stop her from smoking. The drama beautifully portrayed the internal struggle she felt about her feelings, which made her hesitant to open up to him. In one scene, she left him to be with another boy right in front of him, ignoring his calls and not returning for many days. His anger and frustration were understandable. Although they eventually reunited, the ending was ambiguous, leaving us to speculate that they were together and continuing with their lives. However, I had higher expectations for the conclusion of the story.
