My country is tropical and I never experience winter but this drama totally give me the wrong impression that winter is warm lol. I've always loved stories that take references from books and movies, and this drama did it so well. The lines are poetic, yet in no way cringey. Eunseob's and Yoontaek's loves are the perfect definition of selfless love, and although the women seem selfish, but they love them in their own way. Many might be disappointed by the ending, but for me, it's perfect. For me, the definition of happy ending love doesn't have to be together. Even married couples often need to live apart for years and still a happy couple. It's okay to just meet once in a while. What's important is understanding, trust, and the thought of keeping each other precious. Even though they're not physically together, but their hearts are one. It won't be a happy ending if Haewon had to leave cello and teaching just to stay with Eunseob, and she knew he wouldn't want that either. Therefore, this truly is the best ending for them, and they're happy with that so it's good enough for me.
