Doona! is the very best K-drama I have seen in a long time. It is a refreshing and unique take on the romantic comedy genre, with a complex and relatable female lead.

Bae Suzy delivers a standout performance as Lee Doona, a K-pop idol who is struggling with her mental health and her place in the industry. She is prickly and defensive on the outside, but soft and vulnerable on the inside. When she meets Won-joon (Yang Se-jong), a kind and innocent college student, she begins to let her guard down and rediscover her true self.

The relationship between Doona and Won-joon is heartwarming and believable. They support each other through their respective challenges and help each other to grow. There is no unnecessary melodrama or angst, just two people who are falling in love.

The supporting cast is also excellent, and the side characters are just as interesting and complex as the leads. The drama does a great job of exploring the lives of young people in Korea, and it touches on important topics such as mental health, social media, and the entertainment industry.

Overall, Doona! is a must-watch for fans of K-dramas and romantic comedies alike. It is a well-written, well-acted, and heartwarming drama that will stay with you long after you finish watching it.
